使用C＃公鑰時如何獲得公衆的方法從DLL的== NULL

Question

我想從一個dll找到公共用戶定義的函數時publickeytoken == null

OpenFileDialog obj = new OpenFileDialog(); 
if (obj.ShowDialog() == System.Windows.Forms.DialogResult.OK) 
{ 
    Assembly ass = Assembly.LoadFrom(obj.FileName); 

    // Here its getting Exception because Publickeytoken == null; 
    Assembly a = Assembly.LoadWithPartialName(ass.FullName); 

    Type[] types = a.GetTypes(); 
    foreach (Type type in types) 
    { 
     if (!type.IsPublic) 
     { 
      continue; 
     } 

     MemberInfo[] members = type.GetMembers(BindingFlags.Public 
               | BindingFlags.Instance 
               | BindingFlags.InvokeMethod); 
     foreach (MemberInfo member in members) 
     { 
      Console.WriteLine(type.Name + "." + member.Name); 
     } 
    } 
} 

如何解決這個

即使我嘗試這樣查找publictokenkey它retruns 0字節

  byte[] b = Assembly.GetExecutingAssembly().GetName().GetPublicKeyToken();

你結合的標誌是錯誤的，你可以直接使用ass：

OpenFileDialog obj = new OpenFileDialog(); 
if (obj.ShowDialog() == System.Windows.Forms.DialogResult.OK) 
{ 
    Assembly ass = Assembly.LoadFrom(obj.FileName); 
    foreach(var type in ass.GetTypes()) 
    { 
     MethodInfo[] members = type.GetMethods(BindingFlags.Public | BindingFlags.Instance); 

     foreach (MemberInfo member in members) 
     { 
      Console.WriteLine(type.Name + "." + member.Name); 
     } 
    } 
}
