服务引用生成不正确的方法签名答案

【问题标题】：Service Reference Generates Incorrect Method Signature服务引用生成不正确的方法签名
【发布时间】：2016-01-14 01:09:49
【问题描述】：

我们有一个 asmx Web 服务项目。当我使用 Add Service Reference 选项将它添加到项目中时，一切正常。但是，当我的同事这样做时，他得到了操作合同中定义的方法的错误签名。

通过错误的签名，我的意思是原始方法接收实体作为参数，这些实体在我同事的项目中生成为DataSet 参数（服务引用结构也不同，如图所示。我的同事有更多的东西）。我们正在使用 VS 2013。

发生了什么事？

服务合同

  [ServiceContract]
    public interface INetTransTntIntegration
    {
        [OperationContract]
        string CreateGlbTrns1LineCard(GlbTrns1LineCardEntity ent);

        [OperationContract]
        void CreateGlbTrns1LineCardTest();
    }

【问题讨论】：

邮政编码，不是图片。关键点必须是可谷歌搜索的。
@HenkHolterman 唯一可见的区别似乎是图片中的那个，否则我没有任何线索。您想查看代码的任何特定部分吗？
但它可能是导入对话框中的一个设置。
两个项目是否引用相同的程序集？特别是带有 GlbTrns1LineCardEntity 的那个？还要比较“高级”按钮下的设置。
再检查一次，肯定有什么不同。检查基础知识，不要假设任何事情。不正确的版本似乎不知道实体类型。

标签： c# web-services wcf asmx

【解决方案1】：

我同事的 Visual Studio 出于某种原因没有自动转换实体，因此我必须明确设置这些 dll（包含实体定义/操作）的重用选项，以便识别实体。

在我的情况下，我不必检查任何这些，但它工作正常。

感谢@HenkHolterman 抽出宝贵时间。
