c# - ASP.NET、C#、IIS、MIME 类型、文件上传条件

Question

我在网站上有一个文件上传网络表单，它只需要接受某些格式(或 MIME 类型)...

以下代码工作正常，除了它不会将 .DOCX 文件上传到服务器!这是唯一不起作用的文件类型...我仔细检查了每一行代码，甚至进入 IIS 管理器以确保继承了 .DOCX MIME 类型，并且它们...

有谁知道为什么 .DOCX 文件不会像其他所有文件类型一样上传到服务器？

代码片段:

string savePath = "D:\\HIDDEN PATH HERE";
string fileMsg;

// Before attempting to perform operations
// on the file, verify that the FileUpload 
// control contains a file.
if (FileUpload1.HasFile)
{
    // Check to see that the content type is proper and allowed.
    // DOC: application/doc, appl/text, application/vnd.msword, application/vnd.ms-word, application/winword, application/word, application/x-msw6, application/x-msword
    if (
        FileUpload1.PostedFile.ContentType == "text/rtf" ||
        FileUpload1.PostedFile.ContentType == "application/doc" ||
        FileUpload1.PostedFile.ContentType == "appl/text" ||
        FileUpload1.PostedFile.ContentType == "application/vnd.msword" ||
        FileUpload1.PostedFile.ContentType == "application/vnd.ms-word" ||
        FileUpload1.PostedFile.ContentType == "application/winword" ||
        FileUpload1.PostedFile.ContentType == "application/word" ||
        FileUpload1.PostedFile.ContentType == "application/msword" ||       
        FileUpload1.PostedFile.ContentType == "application/x-msw6" ||
        FileUpload1.PostedFile.ContentType == "application/x-msword" ||
        FileUpload1.PostedFile.ContentType == "application/pdf" ||
                        FileUpload1.PostedFile.ContentType == "application/x-pdf" ||
        FileUpload1.PostedFile.ContentType == "application/vnd.openxmlformats-officedocument.wordprocessingml.document" ||
        FileUpload1.PostedFile.ContentType == "application/vnd.openxmlformats-officedocument.wordprocessingml.template"
        )
    {
        // Get the name of the file to upload.
        String fileName = FileUpload1.FileName;

        // Append the name of the file to upload to the path.
        savePath += strnow + fileName;


        // Call the SaveAs method to save the 
        // uploaded file to the specified path.
        // This example does not perform all
        // the necessary error checking.               
        // If a file with the same name
        // already exists in the specified path,  
        // the uploaded file overwrites it.
        FileUpload1.SaveAs(savePath);

        // Notify the user of the name of the file
        // was saved under.
        //fileMsg = "Your file was saved as " + fileName;
        fileMsg = "";
    }
    else
    {
        fileMsg = "Your file was not an accepted format. Please use PDF, RTF or DOC formats."; 
    }

参见 this answer ，它指向您 this page .

DOCX Mime 类型:

application/vnd.openxmlformats-officedocument.wordprocessingml.document

编辑:抱歉，没有在列表中看到它。如果您想允许 DOCX，为什么不检查“.docx”作为扩展名。

|| FileUpload1.PostedFile.FileName.ToLower().Substring(FileUpload1.PostedFile.FileName.Length - 4) == "docx"
