}

oDataSet.Tables.Add("Data");

推荐答案

您的源代码中有一些奇怪的东西，但它有效，我没有任何错误！



你需要解决的问题是：

There are some strange things in your source code but it works, I've not got any errors!

The things you need to fix are:

string PathSelection = "";
// You have not initialized PathSelection, why shall its length > 0?
//if (PathSelection.Length > 0)
{
    //txtInputfile.Text = PathSelection;
}
// i tried this
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
// FileName has not been initialized!
//saveFileDialog1.InitialDirectory = saveFileDialog1.FileName;
