Enum SpecialType

Identifies well-known types for efficient type checking without string comparisons.

[CompileTime]
public enum SpecialType

Use SpecialType to check if a type is one of the well-known types, or Equals(SpecialType) for comparison. Use GetType(SpecialType) to obtain an IType for a special type.
