错误是

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

namespace JSONFromCS
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e1)
{
List<employee> eList = new List<employee>();
Employee e = new Employee();
e.Name = "Minal";
e.Age = 24;

eList.Add(e);

e = new Employee();
e.Name = "Santosh";
e.Age = 24;

eList.Add(e);

string ans = JsonConvert.SerializeObject(eList, Formatting.Indented);

string script = "var employeeList = {\"Employee\": " + ans+"};";
script += "for(i = 0;i<employeelist.employee.length;i++)";>
script += "{";
script += "alert ('Name : ='+employeeList.Employee[i].Name+'
Age : = '+employeeList.Employee[i].Age);";
script += "}";

ClientScriptManager cs = Page.ClientScript;
cs.RegisterStartupScript(Page.GetType(), "JSON", script, true);
}
}
public class Employee
{
public string Name;
public int Age;
}
}

Error   5   Too many characters in character literal    E:\New folder\homepage\Default.aspx.cs  39  21  homepage

推荐答案

所有你需要的是更准确地写字符串，并提出问题。使用HTML元素pre使用正确的格式：

All you need is to be more accurate in writing strings, and asking questions, too. Use proper formatting using the HTML element "pre":

<pre lang="C#">
   … your code here …
</pre>

另请参阅我对该问题的评论。



这是我的建议：停止使用这些字符串连接（很少是个好主意），使用方法的String.format 。请自行修改您的代码;这太微不足道了。你需要让自己能够流利地使用这些东西。



祝你好运。

See also my comment to the question.

Here is my advice: stop using these string concatenation (rarely a good idea), use the method string.Format. Please fix your code by yourself; this is way too trivial. You need to make yourself fluent in such things.

Good luck.
