如何检索泛型方法的名称，包括泛型类型名称

问题描述

在

我可以提供 typeof（T）作为 GetMethodName（） code>（它会起作用），但它会针对泛型类型的数量，例如：with Load< T，U> 它不会工作，除非我提供了另一个参数。

解决方案

在您的要求方面是正确的。事实上，您的解决方案返回 T ，并且他返回运行时类型名称。如果你要求不同的东西，那就试着重写你的问题。下面是一个通用项目的另一个解决方案：

  using System; 
使用System.Collections.Generic; 
使用System.Linq; 
 
类程序
 {
 static void Main（）
 {
 Load（new Repository< int>（））; 
 Load（new Repository< string>（））; 
 Console.ReadLine（）; 
} 
 
类存储库< T> {} 
 
静态列表< T> Load< T>（Repository< T> repository）
 {
 Console.WriteLine（Debug：List< {1}> Load< {1}>（{0}< {1} （Repository< T>），typeof（Repository< T>）。 
返回默认值（List< T>）; 
 
 
 $ / code $ / pre 
 
 
以下是你要求的输出： p> 
 
  
In C#, I have a method with the following signature :
List<T> Load<T>(Repository<T> repository)
Inside Load() method, i'd like to dump full method name (for debugging purposes), including the generic type. eg : calling Load<SomeRepository>(); would write "Load<SomeRepository>"
What i have try so far : using MethodBase.GetCurrentMethod() and GetGenericArguments() to retrieve information.
List<T> Load<T>(Repository<T> repository)
{
   Debug.WriteLine(GetMethodName(MethodBase.GetCurrentMethod()));
}

string GetMethodName(MethodBase method)
{
     Type[] arguments = method.GetGenericArguments();
     if (arguments.Length > 0)
        return string.Format("{0}<{1}>",
          method.Name, string.Join(", ", arguments.Select(x => x.Name)));
     else
        return method.Name;
}
Retrieving method name works, but for generic parameter it always return me "T". Method returns Load<T> instead of Load<SomeRepository> (which is useless)
I have tried to call GetGenericArguments() outside GetMethodName() and provide it as argument but it doesn't help. 
I could provide typeof(T) as a parameter of GetMethodName() (it will works) but then it will be specific to number of generic types eg : with Load<T, U> it would not work anymore, unless I provide the other argument.
 解决方案 
The answer of Jeppe Stig Nielsen is correct in terms of your requirements. In fact, your solution returns T and his returns the runtime type name. If you ask for something different, then try to rewrite your question. The below is another solution for one generic item:
using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        Load(new Repository<int>());
        Load(new Repository<string>());
        Console.ReadLine();
    }

    class Repository<T> { }

    static List<T> Load<T>(Repository<T> repository)
    {
        Console.WriteLine("Debug: List<{1}> Load<{1}>({0}<{1}> repository)", typeof(Repository<T>).Name, typeof(Repository<T>).GenericTypeArguments.First());
        return default(List<T>);
    }
}
Here is the output that you asked for:
