How to pass generic object in WCF Service as parameter?

pass generic list as parameter c#

I don't specify what is the type of the object. It would be better to have overloaded methods operations with their name attribute set to different names. Here is code of Main function. ToList : null; } In fact, reading into your question further, it looks like you want to instantiate a new object of some type and set it's value property to the item in giver. But if you want to continue with your previous approach, you really need something common between your objects and you can achieve that with either a base class, or interface. ReadLine ; } } } Here is sample output.

A neat little type inference trick with C#

pass generic list as parameter c#

For the simple class above it could be implemented like this: public class Wrapper { public static Wrapper Create T wrapped { return new Wrapper wrapped ; } } Anyone who needs an instance of the class can now create it without explicitly specifying the type parameter, as exemplified below. Unless the three classes share a base class, you can't pass a collection of them to a method, except as a collection of object instances, any more than you could write a method that would take a single instance of any of the three classes, unless there is a direct conversion from A to B and vice versa. Add tempGiver ; } } } This is my code. } As at least that way you can check more easily, and retain some strong typing. However, I want to make the GetDictionary method generic so that I can pass a a list of different object types. This question is actually a continuation of my previous question. I've done a bit of digging to try to find a solution myself, but haven't found anything that more or less tailors to what I'm trying to do.

And the entity can be a single Client or a collection of Clients or may be a single Employee or a Collections of Employees and so on. CreateType ; } You can then call it with the type provided explicitly or implicitly, depending on the situation. It seems you are not sharing much code from one List type to another anyway. Please mark the response as answers if it solves your question or vote as helpful if you find it helpful. But the problem is that we are not able to access the property of Second class within first class. I'm trying to past a generic list from C to F , run some calculations and then return a generic list back to C.

However, I do want to have the conversion logic in my LookupList class. You can create instances of this Class, and you can then set the values of the Public Properties in the created instances. But the problem is wcf service don't take any kind of generic object as a parameter. The question is : how can we somehow give the type information to method so it doesn't break at runtime? Whenever you want to add some SomeCustomClass item to the list, you simply create an instance of the dynamic type using the Activator. In this above example we created two classes.

Reverse I get an error on the C side saying I'm trying to call a 'void', which of course doesn't return anything. What I want to do is something like below: In the Client side the method will be. Pass C class as a parameter of another class In this article we will learn to pass one class as a parameter of another class. Reverse x As you noticed, List. That's how you define generic parameters. In particular, whatever object you want to deal with needs to have a GenericTypeId property.

Passing different type parameters to the same C# method

MakeGenericType So how can you create a List, or any other generic type for that matter, that contains objects of a type that is unknown when you compile the application? For updates about new posts, sites I find useful and the occasional rant you can. I'm not sure I completely understand what it is you're trying to do, but your method doesn't seem well-suited for generics. Luckily, there is a MakeGenericType method in the System. Chances are they have and don't get it. This post will explain what you need to do in order to be able to use such a dynamically loaded type from a dynamically loaded assembly as a generic type parameter when you create an instance of some generic class in your application.

C#: Generic Type Parameters And Dynamic Types

Length - 5 ; } private UserType GetUserType UserTypeBase type { return type. Add reportParameter ; } } public void AddParameter string parameterName, string parameterValue { if! However, specifying the type parameter for the Where method is redundant as the compiler can infer them from the parameters. In this case, taker is storing a generic type of object. CreateInstance method and add it to the list using the Add method: Add someCustomClassInstance ; Note that if you try to add an object of any other type than SomeCustomClass in this case, it will result in a System. Or better yet, you should just return the List! What you show us is a Class definition with Attributes related to Serialization, and two Public Properties. ArgumentException since the customListInstance is really a List that only accepts SomeCustomClass objects. Create 42 ; We could also extend the non-generic class to have an extension method for object enabling us to create instances of the generic class by invoking the extension method on any object.

Passing generic list as parameter between F# and C#

When I called the function I wanted to pass the type that I was looking for if it was Materials or Flares that were being indexed. But to be honest you would be better off rethinking this approach. In below example we will try to implement one complete example of parameterized class. What I'm doing is that I've got a function that populates a Hashtable with different assets that have different custom labels. Hope you have learned the concept. I created a generic method private void BindComboBox. The Second class is our main class which we are passing as a parameter of First class.

How can I make a generic method where you pass a generic type and List as a method parameter?

pass generic list as parameter c#

But Is there any way to do the same some how. In the method GetUserType, I want to pass UserBaseType as a parameter, which is a generic abstract class that takes a Type of UserType. I am still not sure how to do this. I have tried to pass a type parameter to the private method to declare generic type list. Am i following correctly here? If you know exactly which assemblies and types you are going to use beforehand, you should add a reference to the assembly and use the types in it as usual. After that's done you can create your method with generics.

Pass C# class as a parameter of another class

pass generic list as parameter c#

This article demands little knowledge of parameterized class. If you are completely new in this concept then below paragraph is for quick understanding of same. Any help or hints would be highly appreciated. In broad sense ,we are trying to create parameterized class where we will pass another class as parameter and we will use the property of the parameter class. Another solution I just discovered would be to use a new feature in C 4.
