在我的网络服务中,我必须在复杂元素中传递复杂元素的列表。
我的第一堂课是:
public List<JBCredential> JBCredentials{ get; set; }
public string codes { get; set; }
public string db { get; set; }
public string locale { get; set; }
public string location { get; set; }
public string mode { get; set; }
public string postcode { get; set; }
在上面的课程中,我必须发送另一个课程的列表,如下所示:
public string code { get; set; }
public string Username { get; set; }
public string Password { get; set; }
现在我想将上面的类发送到我的方法。但是当我将第二类添加到第一类列表时,我收到以下错误
Object reference not set to an instance of an object.
请帮我解决这个问题。
我试过以下
test.request s=new test.request();
test.JBCredential jb = new test.JBCredential();
jb.code = "LNK";
jb.Username = "";
jb.Password = "";
/
s.query = "java";
s.mode = "mock_search";
s.JBCredentials.Add(jb);//I'm not getting add method
so I've tried like this
s.JBCredentials[0].code = jb.code;
s.JBCredentials[0].Password = jb.Password;
s.JBCredentials[0].Username = jb.Username;
and also I tried
List<JBCredential> ad=new List<JBCredential>();
ad.Add(jb);
s.JBCredentials=ad;
我能够从正常请求将值传递给 JBcredentials 类型,但是当我调用 Web 服务时我无法传递这种类型。
