Failure to get generic type SortedList in Type.GetType()

[djpenton]

Hi All,

Seems to be a specific failure with SortedList in getting type from
name. Is this a problem with the .NET framework?

When I run this line in the immediate window:
Type.GetType(typeof(SortedList<double,double>).ToString(),true)

I get
Could not load type 'System.Collections.Generic.SortedList`2' from
assembly 'mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089'.

These work:
Type.GetType(typeof(List<double>).ToString(),true)
Type.GetType(typeof(List<double>).FullName,true)
Type.GetType(typeof(double).ToString(),true)
Type.GetType(typeof(double).FullName.true)
typeof(SortedList<double,double>).FullName
typeof(SortedList<double,double>).ToString()

These fail:
Type.GetType(typeof(SortedList<double,double>).FullName,true)
Type.GetType(typeof(SortedList<int,int>).FullName,true)
Type.GetType(typeof(SortedDictionary<double,double>).FullName,true)
Type.GetType(typeof(SortedDictionary<double,double>).ToString(),true)

I have run out of things to try and test for. Let me know if you have
any ideas.

Cheers,
Dave.

No. The difference is that SortedList<TKEy, TValue> and
SortedDictionary<TKey, TValue> are implemented in System.dll while
List<T> and Double are in mscorlib.dll. If you look at the docs for
Type.GetType you'll find that for type names that aren't assembly
qualified, it only looks in Mscorlib.dll and the calling assembly.

Dear Dave,

Use typeof(SortedList<double,double>).AssemblyQualifiedName instead of
ToString or FullName.

Hope this helps.
Cheers,

Thanks Mattias and Moty, quite a difficult one.
