如何调用网络服务方法 [英] how to call web service methods

问题描述

StudentWebService.StudentWebService mStudentWS = new StudentWebService.StudentWebService();

if (mStudentWS.save(mStudentInfo, mSubjectInfoList))
        {
            hidmitvalue.Value = Convert.ToString(mStudentInfo.SysKey);
            butNew.Visible = true;
            butUpdate.Visible = true;
            butDelete.Visible = true;
            butSave.Visible = false;
            Common.ShowMessage("Save Successfully", this.Page);
            result = true;
        }

编译此代码时，错误显示:

when compile this code, Error show:

Error	1	No overload for method ''save'' takes 0 arguments<br />
Error	2	The best overloaded method match for ''StudentWebService.StudentWebService.save(StudentWebService.StudentInfo, StudentWebService.SubjectInfo[])'' has some invalid arguments<br />
Error	3	Argument 1: cannot convert from ''Student.Info.StudentInfo'' to ''StudentWebService.StudentInfo''<br />
Error	4	Argument 2: cannot convert from ''System.Collections.Generic.List<Student.Info.SubjectInfo>'' to ''StudentWebService.SubjectInfo[]''

请给我有关此错误的建议

推荐答案

消息很清楚，您传递给save方法的参数有问题.我想您正在尝试将List<>作为第二个参数传递，同时该方法期望使用SubjectInfo的数组.

尝试以这种方式称呼它:

Message is clear, the params you are passing to the save methods have something wrong. I suppose that you are trying to pass an List<> as a second parameter, meanwhile the method is expecting the array of SubjectInfo.

Try to call it in this way:

if (mStudentWS.save(mStudentInfo, mSubjectInfoList.ToArray()))

干杯！
