DataGridView

Answer 1

我会使用内置功能（GetClipboardContent()方法）

SaveFileDialog dialog = new SaveFileDialog();
dialog.Filter = "Text File|*.txt";
var result = dialog.ShowDialog();
if (result != DialogResult.OK)
    return;

// setup for export
dgvSum.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableAlwaysIncludeHeaderText;
dgvSum.SelectAll();
// hiding row headers to avoid extra \t in exported text
var rowHeaders = dgvSum.RowHeadersVisible;
dgvSum.RowHeadersVisible = false;

// ! creating text from grid values
string content = dgvSum.GetClipboardContent().GetText();

// restoring grid state
dgvSum.ClearSelection();
dgvSum.RowHeadersVisible = rowHeaders;

System.IO.File.WriteAllText(dialog.FileName, content);
MessageBox.Show(@"Text file was created.");
