c# asp.net xml json

C# 在asp.net中创建web服务时删除xml标记,c#,asp.net,xml,json,C#,Asp.net,Xml,Json,我正在asp.net中创建一个Web服务。下面是我得到的答复 <?xml version="1.0" encoding="utf-8"?> <string xmlns="http://tempuri.org/">{"Question1":"do the like the idea of the first speaker?","Option1":"YES","Option2":"NO","Option3":"NOT SURE","Option4":"","Option5"

我正在asp.net中创建一个Web服务。下面是我得到的答复

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">{"Question1":"do the like the idea of the first speaker?","Option1":"YES","Option2":"NO","Option3":"NOT SURE","Option4":"","Option5":"","Type":"button","QID":"q1"}</string>

使用此代码既安全又方便： ASP

在Javascript中，我认为您应该这样做

var start = YOUR_RESPONSE.indexOf('<string ');
start = YOUR_RESPONSE.indexOf('>', start)+ 1;
YOUR_RESPONSE.substring(start, YOUR_RESPONSE.lastIndexOf('</string>'));

var start=YOUR_RESPONSE.indexOf（''，start）+1；
您的_RESPONSE.substring（start，您的_RESPONSE.lastIndexOf（“”））；

您是否可以验证您的web.config是否正确：

1） “将*.ASMX httphandler重新路由到ScriptHandlerFactory”

2） “Json序列化” 您可以将JSONSerialization设置添加到web.config中，以确保Json序列化工作正常：

请在Web方法中使用以下行：

XmlDocument x=新的XmlDocument（）；x、 LoadXml（新的javaScriptSerializer（）.Serialize（Biz.BAL.GetQuestions（）.ToString（））；返回x.DocumentElement.InnerText；上面的asp代码不工作…其在根级别抛出的xml异常数据无效。第1行，位置1。我已经用你的例子测试过了，这是成功的。到底发生了什么？是否发生编译错误或运行时异常？请调试您的代码并检查您的数据是否包含无效字符？并在JS警报数据的每一行前调试它们。其他想法。。。您是否已将属性[System.Web.Script.Services.ScriptService]添加到Web服务中？（可能是的，因为您已经调用了ScriptMethod..）最终想法=重新路由asmx httphandler。。我已经编辑了我的答案。如果这对你没有帮助，我就不知所措了，对不起，你是如何得到上述回答的？请注意，如果您通过webbrowser测试webservice，您将得到与实际ajax调用不同的结果。

var start = YOUR_RESPONSE.indexOf('<string ');
start = YOUR_RESPONSE.indexOf('>', start)+ 1;
YOUR_RESPONSE.substring(start, YOUR_RESPONSE.lastIndexOf('</string>'));
