Field Value

Remarks

This field is required for the ByValArray and ByValTStr members of the System.Runtime.InteropServices.UnmanagedType enumeration. Because the compressed format of the metadata is limited to 0x1FFFFFFF, the range of allowed values for SizeConst are (>= 0 and <= 0x1FFFFFFF).

For additional information, see Default Marshaling for Arrays.
