推荐答案

您可以通过以下方式从文本框中获取文本:

You can get the text out of a textbox by:

string str = textbox.Text;

然后将其写入具有 StreamWriter [ ^ ].

then write it to a file with a StreamWriter[^].

在Form2的按钮Click事件中，使用此代码

Hi,

In button Click event of Form2, Use this code

using (StreamWriter sw = new StreamWriter("my.txt"))
            {
                
                    sw.WriteLine(Form1.Textbox1.Text);
                    sw.WriteLine(Form1.Textbox2.Text);
                    sw.WriteLine(Form1.Textbox3.Text);
                    sw.WriteLine(Form1.Textbox4.Text);
                    sw.WriteLine(Textbox1.Text);
              
            }

TextWriter tw = new StreamWriter("D:\\date.txt");
// write a line of text to the file
tw.WriteLine(TextBox1.Text);//TextBox1 is the id of the textbox

// close the stream
tw.Close();
