WCF Web服务返回json格式数据 [英] WCF web service returning json format data

问题描述

我创建了一个返回json格式数据的WCF Web服务.我的代码如下:

I have created a WCF webservice returning json format data. My code is like below:

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 \，\"名称\:\" xyz \，\"电子邮件\:\" [e-mail] \}"}

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

但是我想要的输出如下:

But I want the output as below:

{"SampleServiceResult": {"Id":"1"，名称":"xyz"，电子邮件":"[e-mail]"}}

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

在输出中添加"\"转义字符.如何删除它并返回有效的json?

In the output it adds "\" escape character. How can I remove this and return valid json?

我试图替换"\"，但是它不起作用.

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

谢谢

推荐答案

通过在代码中进行以下更改，我得到了预期的结果:

I have got the expected out by applying following changes in my code:

1. 将返回类型从字符串更改为流

2. 替换了下面的代码

1. Changed return type from String to Stream

2. Replaced the below code

return (new JavaScriptSerializer().Serialize(dict));

使用

WebOperationContext.Current.OutgoingResponse.ContentType = "application/json; charset=utf-8"; return new MemoryStream(Encoding.UTF8.GetBytes(sData));

WebOperationContext.Current.OutgoingResponse.ContentType = "application/json; charset=utf-8"; return new MemoryStream(Encoding.UTF8.GetBytes(sData));
