   1 //
   2 // Test for conversions that were supposed to be explicit operator
   3 // conversions on UIntPtr and IntPtr, but due to historical reasons
   4 // ended up in the CSC compiler.
   5 //
   6 // See bug http://bugzilla.ximian.com/show_bug.cgi?id=59800 for details
   7 //
   8 // The conversions are:
   9 //   UIntPtr->SByte
  10 //   UIntPtr->Int16
  11 //   UIntPtr->Int32
  12 //   IntPtr->UInt64
  13 //   UInt64->IntPtr
  14 //   SByte->UIntPtr
  15 //   Int16->UIntPtr
  16 //   Int32->UIntPtr
