Description ea 2011-11-04 15:12:12 UTC
It seems like the strings are not being marshaled properly to Mono string types, when evaluating the individual items of the returned strings you find '\0'.

It is problematic to evaluate the contents strings of the DriveInfo objects returned by DriveInfo.GetDrives().  

The lengths of the string don’t match the content of the string making any kind of c# comparison useless. Comparisons always return false, and switch statements on this string values will only match the 'default' case.


DriveInfo[] dInfo =DriveInfo.GetDrives();
int len = dInfo[0].DriveFormat.Length;

In my case dInfo[0].DriveFormat shows a vaue of "hfs", but the length of the string is 13.

The following statement is always false: (dInfo[0].DriveFormat == "hfs")
