如何在表单之间交换数据 [英] How can I exchange data between forms

问题描述

可能的重复:
在表单之间共享数据

我有:

public partial class LoginForm : Form
{
    private string somedata = "somedata";

    public LoginForm()
    {
        InitializeComponent();
    }    
}

我希望 LoginForm 打开另一个表单并将 somedata 发送给它.我该怎么做?

I want LoginForm to open another form and send somedata to it. How can I do this?

推荐答案

首先在你想要传递登录数据的第二个表单上创建一个公共字符串:

First create a public string on your second form you want to pass the data from login:

   public partial class Form2 : Form       
 {  

 public Form2()              
{  
InitializeComponent(); 
}  

    public string messagefromLogin;
    MessageBox.Show(messagefromLogin);

    }

然后在您登录时:

 public partial class LoginForm : Form       
 {  

 public LoginForm()              
{  
InitializeComponent(); 
}   
private string somedata = "somedata";

//Show Form2 and pass the string "somedata"
 private void btnShowForm2_Click(object sender, EventArgs e)
        {
            var frm2 = new Form2{messagefromLogin=somedata}
frm2.Show();
        }

}
