c# - C#(WCF) - 在网络共享驱动器中创建 excel 文件

Question

我的Visual Studio项目存储在C:\Projects项目名称是Project1，文件名是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

            ...

使用调试，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"

看起来不错。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.

有什么建议可以解决这个问题吗？请高手！！（注：不存在PERMISSON问题）

对于网络，我认为您不需要 \server 但需要 \\server，不是吗？
