注解

获取的实例FieldBuilder通过调用DefineFieldDefineInitializedData,或DefineUninitializedDataGet an instance of FieldBuilder by calling DefineField, DefineInitializedData, or DefineUninitializedData.

备注

SetValue目前不支持方法。The SetValue method is currently not supported. 作为一种解决方法,检索FieldInfo通过专用于反映将已完成的类型和调用SetValue设置字段的值。As a workaround, retrieve the FieldInfo by reflecting on the finished type and call SetValue to set the value of the field.
