How can I query IIS for MIME Type Mappings?

Question

How can I programatically read IIS\'s MIME types? I\'d like to use them when I stream data to my clients using WCF.

Any tips, or API would be appreciated

If using ASP.Net 4.5 or higher, you can use System.Web.MimeMapping.GetMimeMapping as follows:

void Page_Init()
{
    string[] extensions = new string[]
    {
        ".pdf",
        ".xls",
        ".xlsx",
        ".ppt",
        ".pptx",
        ".mp3",
        ".ogg",
        ".svg",
        ".pdf",
        ".png",
    };

    foreach (string extension in extensions)
    {
        string mimeType = MimeMapping.GetMimeMapping(extension);
        Response.Write(String.Format("{0} => {1}
",
                extension,
                mimeType
            ));
    }
}

Result:

.pdf => application/pdf
.xls => application/vnd.ms-excel
.xlsx => application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
.ppt => application/vnd.ms-powerpoint
.pptx => application/vnd.openxmlformats-officedocument.presentationml.presentation
.mp3 => audio/mpeg
.ogg => video/ogg
.svg => image/svg+xml
.pdf => application/pdf
.png => image/png
