本文详细介绍了如何在C#中定义和使用静态泛型方法，包括如何获取类型信息、创建方法实例并传入参数进行调用。

class
ClassWithGenericStaticMethod
{

public static void
PrintName<T>(string
prefix) where T :
class

{
        Console.WriteLine(prefix + " " + typeof(T).FullName);
    }
}

// Grabbing the type that has the static generic
method

Type typeofClassWithGenericStaticMethod =
typeof(ClassWithGenericStaticMethod);

// Grabbing the specific static method
MethodInfo methodInfo =
typeofClassWithGenericStaticMethod.GetMethod("PrintName", System.Reflection.BindingFlags.Static | BindingFlags.Public);

// Binding the method info to generic
arguments
Type[]
genericArguments = new
Type[] { typeof(Program)
};
MethodInfo genericMethodInfo =
methodInfo.MakeGenericMethod(genericArguments);

// Simply invoking the method and
passing parameters
// The null parameter is the object to call the method
from. Since the method is
// static, pass null.
object returnValue =
genericMethodInfo.Invoke(null, new object[] { "hello" });
