c# - 如何在 C# 中从 ASP.NET MVC Controller 调用静态方法

Question

如果从 ASP .NET MVC Controller 调用，GetMethod 找不到公共(public)静态方法。(从控制台应用程序它工作正常)。

要解决此虚拟 SaveEntityGenericWrapper 方法。

如何从代码中删除 SaveEntityGenericWrapper？

为什么 GetMethod("SaveEntityGeneric") 返回 null 但 GetMethod("SaveEntityGenericWrapper") 有效如果从 ASP .NET MVC 2 Controller 调用？

如果在 MVC2 中使用部分信任，如何使 SaveEntityGeneric 私有(private)化？

public class EntityBase() {

    public void SaveEntity(EntityBase original)
    { 
        var method = GetType().GetMethod("SaveEntityGenericWrapper");
        // why this line returns null if called from ASP .NET MVC 2 controller:
        // method = GetType().GetMethod("SaveEntityGeneric");
        var gm = method.MakeGenericMethod(GetType());
        gm.Invoke(this, new object[] { original, this });
    }

    // Dummy wrapper reqired for mvc reflection call only. 
    // How to remove it?
    public List<IList> SaveEntityGenericWrapper<TEntity>(TEntity original, TEntity modified)
        where TEntity : EntityBase, new()
    {
        return SaveEntityGeneric<TEntity>(original, modified);
    }

    public static List<IList> SaveEntityGeneric<TEntity>(TEntity original, TEntity modified)
                where TEntity : EntityBase, new()
    { ... actual work is performed here  }
}

您需要在 GetMethod 中指定 BindingFlags调用以便返回静态方法(我认为默认情况下只返回公共(public)实例方法)

 var method = GetType().GetMethod("SaveEntityGenericWrapper",
                                  BindingFlags.Static|BindingFlags.Public);
