Wcf Web服务返回json格式数据 [英] Wcf web service return json format data

问题描述

您好



我使用c＃创建了WCF webservice并返回了json格式数据。我的代码如下：

Hello

I have created WCF webservice using c# and it return json format data. My code is like below:

public string SampleService(Stream data)
{
	string sJSONdata = "";

	StreamReader reader = new StreamReader(data);
	sJSONdata = reader.ReadToEnd();

	//'now convert the JSON into a data table
	DataTable dt = GetJSONTable(sJSONdata);
	dt.TableName = "Customer";

	Dictionary<string, string> dict = new Dictionary<string, string>();
	foreach (DataRow rs in dt.Rows)
	{
	    dict = new Dictionary<string, string>();
	    foreach (DataColumn col in dt.Columns)
	    {
	        dict.Add(col.ColumnName, rs[col].ToString());
	    }
	}
	return (new JavaScriptSerializer().Serialize(dict));
}

我得到以下输出：

{SampleServiceResult：{\Id\： \1 \，\姓名：\xyz \，\email \：\[e-mail] \}}}



我想要输出如下：

{SampleServiceResult：{Id：1，Name：xyz，email ：[e-mail]}}



在输出中，它在输出中添加\转义字符。如何删除它并在输出中返回有效的json。



谢谢



我是什么尝试过：



我试图替换\但它不起作用。

And I get the following output:
{ "SampleServiceResult": "{\"Id\":\"1\",\"Name\":\"xyz\",\"email\":\"[e-mail]\"}" }

I want output as below:
{ "SampleServiceResult": {"Id":"1","Name":"xyz","email":"[e-mail]"} }

In output it add "\" escape character in output. How can I remove this and return valid json in output.

Thanks

What I have tried:

I have tried to replace "\" but it doesn't work.
