How Can I Dynamically Invoke Generic Methods in C#?

C#dynamic calling the generic method details

In C#programming, we often encounter the type parameters of the generic method when runtime rather than compile. At this time, a dynamic call method is needed. This article will gradually explain how to achieve this goal.

The first step: use the reflection method information

First of all, we need to use reflection to obtain information about generic methods. In the example code, we use the method to obtain method information.

Step 2: Construct a generic method GetMethod(nameof(Sample.GenericMethod))

Next, we need to use the type parameters obtained by dynamically to build a generic method. This can be implemented through the method, where is a dynamic

object.

MakeGenericMethod(myType) Step 3: Call the generic method myType Type

Finally, we can use the

method to call the constructed generic method. For static methods, the first parameter of the method should be .

Invoke Invoke In the example, the code after calling null is as follows:

Summary

Dynamic calling the generic method is a powerful technology in C#. Mastering how to use reflexes to achieve this function can help developers handle scenes where type parameters cannot be determined during compilation. GenericMethod<T>
