Exceptions

InvalidOperationException

The containing type has been created using CreateType().

ArgumentException

The field is not one of the supported types.

-or-

The type of defaultValue does not match the type of the field.

-or-

The field is of type Object or other reference type, defaultValue is not null, and the value cannot be assigned to the reference type.

Remarks

defaultValue is restricted to the following types: Boolean, SByte, Int16, Int32, Int64, Byte, UInt16, UInt32, UInt64, Single, Double, DateTime, Char, String, and Enum. If the field type is a reference type, CLS compliance requires defaultValue to be null. However, starting with the .NET Framework 4, defaultValue can be non-null for a reference type as long as the value can be assigned to that reference type. For example, an Int32 value can be assigned to a field of type Object. This is not CLS-compliant, but it can be useful in interop scenarios.
