Message in Chinese (Simplified) (中文(简体))
协定“<var>Contract Name</var>”中的操作“<var>X</var>”已有“<var>Y</var>”行为,因此不能添加新行为。这通常表示已为此操作调用了 IOperationSerializer.ApplyToOperation 方法。
Unlocalized message
Operation '<var>X</var>' in contract '<var>Contract Name</var>' already has a '<var>Y</var>' behavior, so a new one cannot be added. This usually indicates that the IOperationSerializer.ApplyToOperation method has already been called for this operation.
