Question

我的visual studio项目存储在C:\Projects中，项目名称为Project1，文件名为Test.xls

string directory = AppDomain.CurrentDomain.BaseDirectory;
// directory = C:\\Projects\\Project1 (local drive)

directory = directory.Remove(0, 2);
// directory = \\Projects\\Project1

string newDirectory = "\\server" + directory; 
// newDirectory = \\server\\Projects\\Project1 (now, network shared drive)

string pathCreate = System.IO.Path.Combine(newDirectory, file);
// pathCreate = \\server\\Projects\\Project1\\Test.xls
string excelConStr = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + pathCreate + @"; Extended Properties=""Excel 8.0;HDR=Yes; MultipleActiveResultSets=True"";";

private void CreateExcel(string excelConStr)
    {
        DataTable table = new DataTable();
        using (OleDbConnection excelCreateCon = new OleDbConnection(excelConStr))
        {
            OleDbCommand excelCreateCmd = new OleDbCommand();
            excelCreateCmd.Connection = excelCreateCon

            ...

使用debug，excelConStr返回

"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=\\server\\Projects\\Project1\\Test.xls; Extended Properties=\"Excel 8.0;HDR=Yes; MultipleActiveResultSets=True\";"

excelCreateCmd.Connection.DataSource returns "\\server\\Projects\\Project1\\Test.xls"

看起来很好。但是，它给了我以下错误：'C:\server\Projects\Project1\Test.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.

有任何解决此问题的建议吗？请高手!! （注意：没有PERMISSON问题）

对于网络，我认为你不需要\ server而不是\\ server，不是吗？
