Message in Chinese (Simplified) (中文(简体))
类型“<var>Type Name</var>”无法添加到已知类型的列表，因为已经存在另一个数据协定名称也为“<var>Y</var>:X”的类型“<var>X</var>”。
Unlocalized message
Type '<var>Type Name</var>' cannot be added to list of known types since another type '<var>X</var>' with the same data contract name '<var>Y</var>:X' is already present. If there are different collections of a particular type - for example, List<test> and Test[], they cannot both be added as known types. Consider specifying only one of these types for addition to the known types list.</test>
