使用Web服务中的数据传输对象

Question

我正在尝试编写一个使用Web服务和DTO检索客户信息的C＃Windows应用程序。

我必须使用提供的使用DTO（数据传输对象）的网络服务

在Soap UI中，请求XML看起来像

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:open="http://www.openuri.org/">
   <soapenv:Header/>
   <soapenv:Body>
      <open:getCustomer>
         <open:customerNumber>123456</open:customerNumber>
      </open:getCustomer>
   </soapenv:Body>
</soapenv:Envelope>

DTO回报为

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
   <env:Header/>
   <env:Body>
      <getCustomerResponse xmlns="http://www.openuri.org/" xmlns:ns2="http://www.openuri.org">
         <getCustomerResult>
            <Name>Customer Name</Name>
            <Address1>Address 1</Address1>
            <Address2>Address 2</Address2>
            <City>City</City>
            <State>State</State>
            <Zip>zip</Zip>
         </getCustomerResult>
      </getCustomerResponse>
   </env:Body>
</env:Envelope>

现在，在Visual Studio中添加Web引用之后，我可以调用实例化Web服务，并通过以下方式传递成员ID。

public void getCompanyGreeting(int inCustomerNumber)
    {
        WebReference.getCustomer getCustomerInfo = new WebReference.getCustomer();
        getCustomerInfo.customerNumber = inCustomerNumber;          
    }

问题是如何获取DTO返回的数据，以便可以将其写到表单上的相应文本字段中？

使用Visual Studio时，我希望看到类似getCustomerInfo.Address1的内容，但是由于数据在DTO中，因此无法使用此方法看到返回值。 如果我实例化getCustomerResponse DTO，我会看到getCustomerResponse.Address1，但是我无法将inCustomerNumber值传递给它，因为它不接受输入参数。

Dataflow =用customerNumber调用getCustomer，它返回getCustomerResponse DTO中的所有值。

我的服务代码如下

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34234")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="http://www.openuri.org/")]
public partial class getCustomer {

    private int customerNumberField;

    /// <remarks/>
    public int customerNumber {
        get {
            return this.customerNumberField;
        }
        set {
            this.customerNumberField = value;
        }
    }
}

对于它创建的DTO

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34234")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://www.openuri.org/")]
public partial class AccountDTO {

    private string nameField;

    private string address1Field;

    private string address2Field;

    private int cityField;

    private string stateField;

    private string zipField;

    /// <remarks/>
    public string Name {
        get {
            return this.nameField;
        }
        set {
            this.nameField = value;
        }
    }

    /// <remarks/>
    public string Address1 {
        get {
            return this.address1Field;
        }
        set {
            this.address1Field = value;
        }
    }

    /// <remarks/>
    public string Address2 {
        get {
            return this.address2Field;
        }
        set {
            this.address2Field = value;
        }
    }

    /// <remarks/>
    public int City {
        get {
            return this.cityField;
        }
        set {
            this.cityField = value;
        }
    }

    /// <remarks/>
    public string State {
        get {
            return this.stateField;
        }
        set {
            this.stateField = value;
        }
    }

   /// <remarks/>
    public string Zip {
        get {
            return this.zipField;
        }
        set {
            this.zipField = value;
        }
    }
}

我必须使用的WSDL

Answer 1

您说过， If I instantiate the getCustomerResponse DTO I do see getCustomerResponse.Address1 but I can not pass the value inCustomerNumber to it because it does not accept input parameters. -您不能将任何参数作为类而不是方法传递给它。

您可以按照以下方式调用帐户服务并获得所需的输出：

WebReference.getCustomer cust = new WebReference.getCustomer();
cust.customerNumber = 123456; //pass customer number
WebReference.AccountService acService = new WebReference.AccountService();
WebReference.getCustomerResponse acServiceResponce = acService.getCustomer(cust); //pass object of getCustomer class to getCustomer method  
string address1 = acServiceResponce.getCustomerResult.Address1;
string city = acServiceResponce.getCustomerResult.City;

希望这可以帮助您从此Web服务获得响应
