c# 查询数据生成XML压缩后，通过webservices传输至服务器

1、生成XML并压缩；

DataTable dt2 = DBHelperPg.ExecuteDataTable(sql);
 dgvStore.DataSource = dt2;

 string xmlFilename = "666.xml";
 FileStream fsWriteXml = new FileStream(xmlFilename, System.IO.FileMode.Create);
dt2.WriteXml(fsWriteXml);
  fsWriteXml.Close();
ZipHelper.ZipFile("666.xml", "666.zip");

MessageBox.Show("压缩成功");

二、引用webservice

1、在“引用”上点右键，选“添加引用服务”

 （图一）

  2、输入引用的网址，点“转到”，再输入命名空间，点确定；

 (图二)

   3、系统的App.config文件中会多出以下内容：

 （图三）

 4、在程序中，随便添加一个按钮，输入以下代码

            LrWebDDI.CommonWebServiceClient myWebService = null;
            myWebService = new LrWebDDI.CommonWebServiceClient("CommonWebServiceImplPort");
            string xmlFilename = "666.zip";
            var byteArray = FileToByteArray(xmlFilename);
            myWebService.upload(byteArray, @"d:\666.zip");
            MessageBox.Show("ok");

其中，LrWebDDI是图二中第3步输入的命名空间；

猜测：CommonWebServiceClient 这个就是webservice名称+“client",（在图一步骤2，点“转到”，展开“服务”下面的列表，可以看到“具体原因不明，纯抄作业试出来的）；

myWebService = new LrWebDDI.CommonWebServiceClient("CommonWebServiceImplPort");
括号中的这个参数写不对，系统会提示错误”在 ServiceModel 客户端配置部分中，找不到引用协定“*****”的默认终结点元素。这可能是因为未找到应用程序的配置文件，或者是因为客户端元.”之类错误；

我是在App.config文件中，一个一个试出来的；见“图三”的标红处
