Question

c#winform导出txt文件

Answer 1

前几天刚写过的，其实很简单的。这里上代码你可以参考一下
private void buttonX2_Click(object sender, EventArgs e)
{
SaveFileDialog saveFile1 = new SaveFileDialog();
saveFile1.Filter = "文本文件(.txt)|*.txt";
saveFile1.FilterIndex = 1;
if (saveFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK && saveFile1.FileName.Length > 0)
{
System.IO.StreamWriter sw = new System.IO.StreamWriter(saveFile1.FileName, false);
try
{
sw.WriteLine(textBoxX5.Text); //只要这里改一下要输出的内容就可以了
}
catch
{
throw;
}
finally
{
sw.Close();
}
}
}

用流streamwriter写进你在外面的txt，大概是streamwriter sw=new streamwriter("路径");
sw.writeLine(textbox.text);

if (System.IO.File.Exists(path))
System.IO.File.AppendAllText(path, contents, Encoding.UTF8);
