推荐答案

您可以通过构造函数将变量从From1传递到Form2.在按钮单击事件中写入以下内容，以将Form1中的TextBox1值传递给Form2中的TextBox1:

Hi,
You can pass variable from From1 to Form2 through constructor. Write following in button click event to pass TextBox1 value in Form1 to TextBox1 in Form2 :

string data = TextBox1.Text;
Form2 obj = new Form2(data);
obj.Show();

In Form2 create a constructor like this:
Form(string data)
{
     this.TextBox1.Text = data;
}

class form1
{
   type var1;
}

class form2
{
   type var2=form1.var1;
}

form1


按钮click_event

form1


Button click_event

string name="Sham";

form2 frm=new form2();
frm.name1=name;
frm.show();this.hide();

form2

表单加载事件

form2

form load event

string name1;

textbox1.text=name1.tostring();
