Question

我想在另一个webservice调用中使用webservice调用的结果，就在它之后......但是第二个webservice在第一个webservice的结果之前被调用.......我正在使用wp7 app .....

PhoneService.WebServiceSoapClient register = new PhoneService.WebServiceSoapClient();

register.InsertNewCollegeCompleted += register_InsertNewCollegeCompleted;               
register.InsertNewCollegeAsync(newCollegeName);
register.InsertNewCollegeCompleted += register_InsertNewCollegeCompleted;

register.insertdataCompleted += register_insertdataCompleted;            
register.insertdataAsync(Name.Text, email.Text, contact.Text,
        int.Parse(partnerid.Text.Substring(2)), student_no.Text, pass.Text,
        gender, branchid, yearid, collegeid, shirtreqd, accom);
register.insertdataCompleted += register_insertdataCompleted;

void register_insertdataCompleted(object sender, PhoneService.insertdataCompletedEventArgs e)
{
    MessageBox.Show("TT ID is" + e.Result);
}

void register_InsertNewCollegeCompleted(object sender, PhoneService.InsertNewCollegeCompletedEventArgs e)
{
    collegeid = e.Result;
}

Answer 1

您可以使用Asynccalls，您基本上想先使用注册，然后在您的登录Api中使用它的响应。
我通过使异步调用等待来完成此操作，您可以查看链接。 http://developer.nokia.com/community/wiki/Asynchronous_Programming_For_Windows_Phone_8 而且这也会有所帮助：

Answer 2

在第一次服务呼叫的已完成方法中执行第二次Web服务调用

在您的情况下，调用register_InsertNewCollegeCompleted中的register.insertdataAsync方法

{
....
....
            PhoneService.WebServiceSoapClient register =
     new PhoneService.WebServiceSoapClient();

            register.InsertNewCollegeCompleted += register_InsertNewCollegeCompleted;               
            register.InsertNewCollegeAsync(newCollegeName); 
....
....
}



    void register_InsertNewCollegeCompleted(object sender, PhoneService.InsertNewCollegeCompletedEventArgs e)
        {
            collegeid = e.Result;
    register.insertdataCompleted += register_insertdataCompleted;            
        register.insertdataAsync(Name.Text, email.Text, contact.Text,
                int.Parse(partnerid.Text.Substring(2)), student_no.Text, pass.Text,
                gender, branchid, yearid, collegeid, shirtreqd, accom);
        }

    void register_insertdataCompleted(object sender, PhoneService.insertdataCompletedEventArgs e)
    {
        MessageBox.Show("TT ID is" + e.Result);
    }
