類型的「System.Runtime.InteropServices.COMException」發生未處理的異常

Question

這裏是我的代碼：

    string path = @"Y:\Audit Reports\"; 
    if (fileName.Length >= 1) 
    { 
     MyConn.Close();

我已經試過我知道解決問題的一切。什麼可能導致這個問題？任何想法的主意是讚賞！

您設置的安全性爲Y:\Audit Reports\是可以寫可讀的。我希望它能幫助你。

string fileName = "Audit_Reports_" + string.Format("{0:MM-dd-yyyy}", dt) + ".xls";
