Unexpected value of System.Type.FullName

I recently needed to build C# specific name (which must always include global:: specifier) for an arbitrary type and have come accross following issue:

// 1 - value: System.String[,,,][,,][,]
string unexpectedFullName = typeof( string[,][,,][,,,] ).FullName;      

// 2 - value: System.String[,][,,][,,,]
string expectedFullName = Type.GetType( "System.String[,][,,][,,,]" ).FullName;

I was expecting that returned value would be same in both cases. However, for some reason the array related part of the value seems to be reversed (case 1). Is this reversal expected behavior?
