case DialogResult.No: ,我得到了错误:

访问被拒绝

private void button1_Click(object sender, EventArgs e)
{
    var message = "Love?";
    var title = "Love?";
    var result = MessageBox.Show(message, title, MessageBoxButtons.YesNo, MessageBoxIcon.Question);

        case DialogResult.No:
            string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
            string text2write = "LOVE";
            System.IO.StreamWriter writer = new System.IO.StreamWriter(desktopPath);
            writer.Write(text2write);

您忘记指定文件路径。

string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string text2write = "LOVE";
System.IO.StreamWriter writer = new System.IO.StreamWriter(desktopPath+"\\abc.txt");
writer.Write(text2write);
writer.Close();

它将为您创建abc文本文件。如果创建了一个aleary文件,那么只需指定确切的路径并将其设置为true。

new System.IO.StreamWriter(string path,bool append);

例子:

new System.IO.StreamWriter(desktopPath+"\\abc.text",true);
