Can I Make Extension Methods For System.IO.Path Class? [duplicate]

Question

How Can I Make Extension Method For System.IO.Path Class what i mean that i need something like below:

Path.GetExtension(sFilePath) 

i want to make method:

Path.GetMimeType(sFilePath)

Extension Method:

public static string GetMIMEType(this Path sPath,string sFilePath)
{
        string sExtension = Path.GetExtension(sFilePath).ToLowerInvariant();

        if (sExtension.Length > 0 && dicMIMETypes.ContainsKey(sExtension.Remove(0, 1)))
        {
            return dicMIMETypes[sExtension.Remove(0, 1)];
        }
        return "unknown/unknown";
}

but when compile above code method get error ('System.IO.Path': static types cannot be used as parameters).

Thanks All,

Path is static, and therefore you cannot create an extension method for it. Extension methods require an instance of an object.
