推荐答案

有'丑陋''：在控件（例如文本框）上写下你的消息，然后同步启动文件发送操作，结果是冻结UI的结果。

有'正确的方法'：开始你的文件发送操作在工作线程上，这样GUI就会保持响应。

There is 'the ugly way': write your message on a control (e.g. a textbox) and then start synchronously the file sending operation, with the net effect of freezing the UI.
There is 'the proper way': start your file sending operation on a worker thread, this way the GUI would remain responsive.

HI
你可以尝试这样。



创建并设计一个窗体，类似于 messagebox 外观。

为它添加一个标签，上面写着请等待...



并执行以下操作

HI you can try like this.

Create and design a windows form similar to messagebox look and feel.
add a label to it saying " Please wait..."

and do the following

private void btnSendFile_Click(object sender, EventArgs e)
       {
           Form2 frmMessageBox = new Form2();
           frmMessageBox.Show();
           // your code for sending file....
           // after your file is sent then you can close the message form
           frmMessageBox.Close();

       }
