使用异常处理处理错误....

Use Exception Handling to handle the error....

private void ShortCut_Load(object sender, EventArgs e)
{
         int value = 0;
         try
         {
                  value = Convert.ToInt32(form2size.Text);
         }
         catch
         {}
         this.Size = new Size(this.Size.Width + value, 130);
}

String Converted= int.Parse(label1.Text);
