通过C# 代码实现webservice 的调用

读取操作

var instance = new WebReference.service1();

        instance.Credentials = new NetworkCredential(“K8NY4FCZOQP”, “Aaaaaaa5”);

        //var instance = new Y3YCI6DOY_WSserviceClient(“binding1”);

        //serviceInstance.c

        //instance.ClientCredentials.UserName.UserName = “K8NY4FCZOQP”;

        //instance.ClientCredentials.UserName.Password = “Aaaaaaa5”;

        AddMultReadByIDQuery addmult = new AddMultReadByIDQuery();

        addmult.OperationID =  this.TextBox5.Text;

        AddMultReadByIDQueryMessage_sync ReadBy = new AddMultReadByIDQueryMessage_sync();

        ReadBy.AddMult = addmult;

        AddMultReadByIDResponseMessage_sync readResponse = new AddMultReadByIDResponseMessage_sync();

        readResponse = instance.Read(ReadBy);

        AddMultReadByIDResponse ReadByID = new AddMultReadByIDResponse();

        ReadByID = readResponse.AddMult;

        this.TextBox1.Text = ReadByID.Value1.ToString();

        this.TextBox2.Text = ReadByID.Value2.ToString();

        this.TextBox3.Text = ReadByID.Result1.ToString();

        this.TextBox4.Text = ReadByID.Result2.ToString();

创建

var instance = new WebReference.service1();

        instance.Credentials = new NetworkCredential(“K8NY4FCZOQP”, “Aaaaaaa5”);

        //var instance = new Y3YCI6DOY_WSserviceClient(“binding1”);

        //serviceInstance.c

        //instance.ClientCredentials.UserName.UserName = “K8NY4FCZOQP”;

        //instance.ClientCredentials.UserName.Password = “Aaaaaaa5”;

        AddMultCreateRequest create = new AddMultCreateRequest();

        create.Value1Specified = true;

        create.Value1 = Convert.ToInt32(this.TextBox1.Text);

        create.Value2Specified = true;

        create.Value2 =Convert.ToInt32(this.TextBox2.Text);

        create.OperationID = this.TextBox5.Text;

        AddMultCreateRequestMessage_sync createRequest=new AddMultCreateRequestMessage_sync ();

        createRequest.AddMult=create;

        AddMultCreateConfirmationMessage_sync creteConfir =  instance.Create(createRequest);

        if (creteConfir!=null)

        {

            if (creteConfir.AddMult.OperationID!=””)

            {

                Response.Write(“<script>alert(‘添加成功’);</script>”);

            }

        }

这里主要的难题是那个验证：instance.Credentials = new NetworkCredential(“K8NY4FCZOQP”, “Aaaaaaa5”);

我试过很多方法，以后可能也会继续研究。不过现在开发需要，只能点到即止了！

在这里我学到了两种方法引用web服务。说是两种其实是一种，因为第二种是在第一种无法实现的情况下（不兼容的情况下）才用。

第一种：

第二种：点击高级→点击引用web服务

其实两种的所填的路径都一样，只是第一种有更严格的验证和保密机制，第二种就相对弱点，都是明文传送容易被截取。

仔细研究.net 根据wsdl自动生成的类，就会发现。有一定的规律在里面。比如：

AddMultReadByIDQueryMessage_sync  查找的类参数

AddMultReadByIDResponseMessage_sync 同步返回的类

AddMultCreateRequestMessage_sync 创建时的参数

AddMultCreateConfirmationMessage_sync 同步返回时的类

和普通的类调用相比，虽然可以看出会多出很多复杂和多余的类，但是还是有一些本来的重要属性在里面。

比如：创建时，需要必填的字段必须设置Value1Specified为true;

create.Value1Specified = true;

        create.Value1 = Convert.ToInt32(this.TextBox1.Text);

        create.Value2Specified = true;

        create.Value2 =Convert.ToInt32(this.TextBox2.Text);
