C＃，创建新表单时如何通过引用传递？ [英] C#, How do I pass by reference when creating a new form?

问题描述

以下代码有效：

The following code works:

private void button1_FastSetup1(object sender, System.EventArgs e)
     {
         WiFi_Fast_Setup_Form1 fs = new WiFi_Fast_Setup_Form1(
             NetworkName_tB.Text,
             PassPhrasetBox.Text,
             emailServer_tB.Text,
             To_Email_textBox.Text,
             CC_Email_tB.Text,
             BCC_textBox.Text,
             subject_TxtBox.Text,
             rTBox_Body_Message.Text
             );
         fs.ShowDialog();
     }

但这不是：

But this does not:

private void button1_FastSetup1(object sender, System.EventArgs e)
{
    WiFi_Fast_Setup_Form1 fs = new WiFi_Fast_Setup_Form1(
        ref string NetworkName_tB,
        ref string PassPhrasetBox,
        ref string emailServer_tB,
        ref string To_Email_textBox,
        ref string CC_Email_tB,
        ref string BCC_textBox,
        ref string subject_TxtBox,
        ref string rTBox_Body_Message
    );
    fs.ShowDialog();
}

使用引用（指向字符串的指针）正是我需要的。

但是怎么做我开始工作了吗？

Using a reference (pointer to string) would be exactly what I need.
But how do I get it to work?

推荐答案

使用System.Windows;







application.current.resources [NetworkName_tB]; //就像网络中的会话

using System.Windows;



application.current.resources["NetworkName_tB"];// is like session in web

'ref'关键字必须位于起始实例上并放在接收函数中。

我的问题是我没有意识到Visual编译器正在查看接收函数调用还没有'ref'关键字。

The 'ref' keyword must reside on the starting instance and be placed in the receiving function.
my problem was that I did not realize that the Visual compiler was looking at the receiving function invocation which did not yet have the 'ref' keyword.
