如何在ASP.NET webform方法中将客户验证消息作为json返回 [英] How do I return custome validation message as json in ASP.NET webform method

问题描述

 catch (Exception ex)
            {
			 throw ex;
				
            }
            finally
            {
                con.Close();
            }


            ArrayList a = new ArrayList();
            a.Add(reportList);
            a.Add(p);
 if (reportList.Count()  != 0)
            {
 return JsonConvert.SerializeObject(a);
            }
			else{
			
			return // "custom message records not found"
}

我尝试过：

What I have tried:

 catch (Exception ex)
            {
			 throw ex;
				
            }
            finally
            {
                con.Close();
            }


            ArrayList a = new ArrayList();
            a.Add(reportList);
            a.Add(p);
 if (reportList.Count()  != 0)
            {
 return JsonConvert.SerializeObject(a);
            }
			else{
			
			return // "custom message records not found"
}

推荐答案

您可以创建对象，然后将其转换为json对象。示例。

You can create object and then convert it to json object. Example.

public class ValidationMessage
{
    public int success { get; set; }
    public string message { get; set; }
}
Usage:

var valMessage = "{\"success\":1,\"message\":\"successfully created.\"}";
return JsonConvert.DeserializeObject<ValidationMessage>(valMessage);

试试这个

只需比较第一个索引值javascript中的json数组

try this
just compare the first index value of the json array in javascript

if (reportList.Count()  != 0)
            {
            a.Add("success");
              a.Add(reportList);
            a.Add(p); 
            }
			else {
            a.Add("failure");
              a.Add("Your custom message");  
        }
             return JsonConvert.SerializeObject(a);
