xxxxxx不是有效的路径。确保路径名是

Question

我有Windows应用程序，该应用程序可以访问我修改过的setting.ini文件中的文件，并可以从我的代码中访问它们。但仍然出现类似'C:\Users\infinity\Desktop\aadinathfiles\ALL EVENT FILE FORMAT\TRADING MASTER FILE\ISE CLEINT MASTER.xls' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

的错误

这是我的setting.ini文件代码：

[UserDetail]
UserID=xxxxxxx
PassWord=xxxxxxxx

[Connection]
contact=C:\Users\infinity\Desktop\aadinathfiles\ALL EVENT FILE FORMAT\TRADING MASTER FILE\ISE CLEINT MASTER.xls
DebitISE=C:\Users\infinity\Desktop\aadinathfiles\ALL EVENT FILE FORMAT\TRADING MASTER FILE\ISE 1.xls
DebitLKP=C:\Users\infinity\Desktop\aadinathfiles\ALL EVENT FILE FORMAT\TRADING MASTER FILE\ISE CLEINT MASTER.xls

[FilePath]
DebitISEClient=C:

[FileName]
DebitISEClient=Contact_06-07-2015.txt

这里是我从ini文件访问此文件的代码：

private void button1_Click(object sender, EventArgs e)
        {

            string filepath = txtpayoutfile.Text;

            string message = "";
            string mobileno = "";
            string name = "";
            DataSet dsmaster = new DataSet();
            string filepathc = ini.IniReadValue("Connection", "contact");
            if (filepath == "")
            {
                MessageBox.Show("Import Contact File");

                this.Show();
            }
            if (Path.GetExtension(filepath) == ".xls")
            {
                oledbConn1 = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepathc + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"");
            }
            else if (Path.GetExtension(filepath) == ".xlsx")
            {
                oledbConn1 = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepathc + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;';");
            }

            oledbConn1.Open(); ////exception occurs here


            if (Path.GetExtension(filepath) == ".xls")
            {
                oledbConn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"");
            }
            else if (Path.GetExtension(filepath) == ".xlsx")
            {
                oledbConn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filepath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;';");
            }

            OleDbCommand cmdoledb = new OleDbCommand("Select * from [Sheet1$3:3000]", oledbConn);
            OleDbDataAdapter daoledb = new OleDbDataAdapter(cmdoledb);
            DataTable dt = new DataTable();
            daoledb.Fill(dt);
}
