System::Windows ::Forms ::SaveFileDialog ^saveFileDialog=gcnew System::Windows ::Forms ::SaveFileDialog ;
saveFileDialog->Filter ="Txt File(*.txt)|*.txt|All File(*.*)|*.*";
saveFileDialog->RestoreDirectory =true;
if (saveFileDialog->ShowDialog() == System::Windows ::Forms ::DialogResult ::OK )
{
FileStream ^fs = gcnew FileStream(saveFileDialog->FileName, FileMode::OpenOrCreate ,FileAccess::ReadWrite );
StreamWriter ^sw = gcnew StreamWriter(fs);

调试一下，捕捉一下异常。
然后看看什么错误信息！
