C#.NET 剪切板复制粘贴泛型的例子代码参考 Clipboard Copy Paste List

             //  这里判断是否有数据被复制
             object  clipboardData  =  Clipboard.GetData( " userEntites " );

         private   void  btnCopy_Click( object  sender, EventArgs e)
        {
             //  读取数据
            List < BaseUserEntity >  userEntites  =   new  List < BaseUserEntity > ();
             for  ( int  i = 0 ; i < this .DTUser.Rows.Count; i ++ )
            {
                BaseUserEntity userEntity  =   new  BaseUserEntity( this .DTUser.Rows[i]);
                userEntites.Add(userEntity);
            }
             //  复制到剪切板
            Clipboard.SetData( " userEntites " , userEntites);
             this .btnPaste.Enabled  =   true ;
        }

         private   void  btnPaste_Click( object  sender, EventArgs e)
        {
             object  clipboardData  =  Clipboard.GetData( " userEntites " );
             if  (clipboardData  !=   null )
            {
                List < BaseUserEntity >  userEntites  =  (List < BaseUserEntity > )clipboardData;
                 string [] addUserIds  =   new   string [userEntites.Count];
                 for  ( int  i  =   0 ; i  <  userEntites.Count; i ++ )
                {
                    addUserIds[i]  =  userEntites[i].Id.ToString();
                }
                 //  添加用户到角色
                ServiceManager.Instance.RoleService.AddUserToRole( this .UserInfo,  this .TargetRoleId, addUserIds);
                 //  加载窗体
                 this .FormOnLoad();
                 //  设置按钮状态
                 this .SetControlState();
            }
