Dynamically create delegation with reflection

Delegate is the basis for implementing events in C #. Sometimes it is inevitable to dynamically create a delegate. In fact, delegate is also a type: system. Delegate. All delegates are derived from this class.
System. Delegate provides some static methods to dynamically create a delegate, such as a delegate:

Namespace testspace {
DelegateString testdelegate (string value );
Public class testclass {
Public testclass (){
}
Public voidGetvalue(String value ){
Return value;
}
}
}

Example:
Testclass OBJ = new testclass ();

// Obtain the type. In fact, you can use typeof to obtain the type.
Type T = type. GetType ("Testspace. testclass");
// Create a proxy, input the type, object for creating the proxy, and method name
Testdelegate method = (testdelegate)Delegate. Createdelegate (T, OBJ ,"Getvalue");

String returnvalue = method ("hello ");
