简介：

今日在做一个WebService,在客户端用SOAP直接调用此WebService,但运行时的结果却怪怪的..

以下是WebService端的代码函数:

/// <summary>

/// 发送邮件

/// </summary>

/// <param name="key">验证密匙</param>

/// <param name="from">发件人</param>

/// <param name="recipients">收件人</param>

/// <param name="subject">主题</param>

/// <param name="body">邮件正文</param>

/// <returns>是否发送成功</returns>

[WebMethod]

public bool Send( string key, string from, string recipients, string subject, string body)

{

if (string.IsNullOrEmpty(from) || string.IsNullOrEmpty(recipients)) return false;

//验证会话

if (!CheckSessionPermission(key)) return false;

try

{

//new EmailSender().Send(from, recipients, subject, body);

return true;

}

catch

{

return false;

}

下面是客户端使用SOAP调用的代码:

/// <summary>

/// 发送邮件

/// </summary>

/// <param name="from">发件人</param>

/// <param name="recipients">收件人</param>

/// <param name="subject">主题</param>

/// <param name="body">邮件正文</param>

/// <returns>是否发送成功</returns>

[SoapDocumentMethod( " http://temp.uri/Service/Email/Send " ,

RequestNamespace = " http://temp.uri/Service/Email/ " ,

ResponseNamespace = " http://temp.uri/Service/Email/ " ,

Use = System.Web.Services.Description.SoapBindingUse.Default,

ParameterStyle = SoapParameterStyle.Wrapped

)]

public bool Send( string from, string recipients, string subject, string body)

{

object[] results = this.Invoke("Send", new object[] { this.Key, from, recipients, subject, body });

return (bool)results[0];

}

下面是一个示例的调用代码:

EmailServiceClient emailClient = new EmailServiceClient( " http://localhost/Service/EmailService.asmx " );

emailClient.Key = " ddd " ;

emailClient.Send( "from @test.com " , " to@test.com" , " 测试的邮件 " , " 这是一封测试的邮件,收到吗？ " );

现在问题就来了.上面的代码运行后,发现参数有移位现象!!即WebService端函数里参数获取到的值为:from="ddd",recipients="from@test.com",subject="to@test.com",body="测试的邮件".而key的值却是null

弄了几次都是一样的情况.搞不懂.不知是什么原因导致的:(

后来再写了一个测试函数,却又发现如果客户端(SOAP)里的传递参数名如果和WebService里的函数的参数名不同,则其值永远获取不到!永远为null!!但又不会出现参数值偏移的问题!!!
下面就是这个古怪的函数:
WebService代码:

[WebMethod]

public bool Add( int i, string text, string bb)

{

string s = text;

return false;

}

客户端代码:

[SoapDocumentMethod( " http://temp.uri/Service/Email/Add " ,

RequestNamespace = " http://temp.uri/Service/Email/ " ,

ResponseNamespace = " http://temp.uri/Service/Email/ " ,

Use = System.Web.Services.Description.SoapBindingUse.Default,

ParameterStyle = SoapParameterStyle.Wrapped
