出现“找不到路径的一部分”错误

Question

我在我的 Web 应用程序中使用 FileUploader 控件。我想将文件上传到指定的文件夹中。由于具体的文件夹还不存在，我必须在我的代码中创建它的路径。

Could not find part of the path.
mscorlib.dll but was not handled in user code

Additional information: Could not find a part of the path
'C:\Users\seldarine\Desktop\PROJ\ED_Project\SFiles\Submissions\blueteam\Source.zip

我认为我的文件路径有问题。 这是我的代码的一部分：

 //teamName is a string passed from a session object upon login 
 string filePath = "SFiles/Submissions/" + teamName+ "/";

 //If directory does not exist
 if (!Directory.Exists(filePath))
 { // if it doesn't exist, create

    System.IO.Directory.CreateDirectory(filePath);
 }

 f_sourceCode.SaveAs(Server.MapPath(filePath + src));
 f_poster.SaveAs(Server.MapPath(filePath + bb));

Answer 1

试试：

//teamName is a string passed from a session object upon login 
 string filePath = "SFiles/Submissions/" + teamName+ "/";
 string severFilePath = Server.MapPath(filePath);
 // The check here is not necessary as pointed out by @Necronomicron in a comment below
 //if (!Directory.Exists(severFilePath))
 //{ // if it doesn't exist, create

    System.IO.Directory.CreateDirectory(severFilePath);
 //}

 f_sourceCode.SaveAs(severFilePath + src));
 f_poster.SaveAs(severFilePath + bb));

您需要检查和创建基于Server.MapPath(filePath); 的目录，而不是filePath（我假设您的src 和bb 是没有任何子目录路径的文件名）。

最好使用Path.Combine而不是串联字符串：

f_sourceCode.SaveAs(Path.Combine(severFilePath,src));
f_poster.SaveAs(Path.Combine(severFilePath,bb));
