[英]writing to disk: File access denied
I try to write my data to an Excel file. 我尝试将数据写入Excel文件。 I'm using workbook method SaveAs.
我正在使用工作簿方法SaveAs。 This is the code:
这是代码:
string FN = "C:\\Users\\Documents\\dane1.xlsx";
WB.SaveAs(FN, Excel.XlFileFormat.xlWorkbookNormal,
Missing.Value, Missing.Value, Missing.Value, Missing.Value,
Excel.XlSaveAsAccessMode.xlShared,
Missing.Value, Missing.Value, Missing.Value,
Missing.Value, Missing.Value);
Everything is OK while the first parameter is hardcoded. 硬编码第一个参数后,一切正常。 When I try use a reference to object where I'm keeping path and file name (I've got it from SaveFileDialog) my application return me an exception:
当我尝试使用对保留路径和文件名的对象的引用(我从SaveFileDialog获取它)时,我的应用程序向我返回异常:
File access denied".
访问文件被拒绝”。
What's wrong? 怎么了? Does anybody know how this can be avoided?
有人知道如何避免这种情况吗?
IF you're running Vista / Windows 7 you may need to run your application as Administrator to save to c:\\Users\\Documents
(which generally doesn't exist) 如果您正在运行Vista / Windows 7,则可能需要以管理员身份运行应用程序以保存到
c:\\Users\\Documents
(通常不存在)
Did you mean c:\\Users\\'username'\\Documents
? 您是说
c:\\Users\\'username'\\Documents
吗?
in C# you could use Environment.GetEnvironmentVariable("userprofile")
to get the users folder (ie c:\\Users\\Postman) - which is like type %userprofile% into run. 在C#中,您可以使用
Environment.GetEnvironmentVariable("userprofile")
来获取用户文件夹(即c:\\ Users \\ Postman)-类似于运行%userprofile%。
