方法无法返回值，错误:无法在 C#、ASP.NET 中转换类型 [英] method can't return value, Error: can not convert type in C#, ASP.NET

问题描述

我有应该返回一组数据的方法.但最后在返回数据时，错误显示为:无法将类型 'WebApplication1.Webrefernce13.DT_value[]' 转换为 'WebApplication1.Webrefernce13.DT_value"

I have method that should return a set of data. But at last when returning data then error shows like :"can not convert type 'WebApplication1.Webrefernce13.DT_value[]' to 'WebApplication1.Webrefernce13.DT_value"

public class InputHelp
{
    public DT_Value Priority()
    {
        WebReference13.DT_SM_InputHelp_Request IncomingtypeReq = new WebReference13.DT_SM_InputHelp_Request();

        WebReference13.DT_SM_InputHelp IncomingTypeResp;
        WebReference13.SI_CreateSM_OBService _proxy1 = new WebReference13.SI_CreateSM_OBService();
        CookieContainer cookie = new CookieContainer();
        _proxy1.Credentials = new NetworkCredential("xxxx", "xxxxx"); // use credential to acess to the SAP system
        _proxy1.CookieContainer = cookie;

        IncomingtypeReq.Mode = "Create";
        IncomingtypeReq.Language = "EN";

        IncomingtypeReq.OptionalText1 = "ZLFN";

        IncomingtypeReq.OptionalText2 = "";
        IncomingtypeReq.WSCallID = "223424dgdf";

        IncomingTypeResp = _proxy1.SI_GetInputHelp(IncomingtypeReq);

        DT_Value[] ab=new DT_Value[10];

        ab= IncomingTypeResp.Priority;

        return ab;  // error is here
    }

如果你能在这个问题上帮助我，我将不胜感激.

I will be grateful if you can help me on this issue.

推荐答案

将您的方法签名更改为

public DT_Value[] Priority(){...}

还有

    DT_Value[] ab=new DT_Value[10];
    ab = IncomingTypeResp.Priority; //<-- something doesn't look right here.

如果 IncomingTypeResp.Priority 是 DT_Value[] 类型，那么你可以这样做

if IncomingTypeResp.Priority is of type DT_Value[] then you can just do

 DT_Value[] ab = IncomingTypeResp.Priority;
