如何连接2个JSON字符串..？ [英] How to concatenate 2 JSON strings..?

问题描述

你好有..

我想连接两个json字符串。

第一个字符串包含数据表记录详细信息，其他字符串包含Count值。

我得到的值在数据集中这样。



数据集ds.Tables [0] = //表记录

ds .tables [1] = //单数整数值（例如TotalCount = 12）



我在json中转换ds但是它返回json字符串。

 {contactList：[{姓名：Abhijit Goswami，电子邮件：[e-mail]，contactNo：9158417355，性别：男性}，{姓名：Abhijit Goswami，电子邮件：abhijitda @ facebook.com，contactNo：9158417355，性别：男性}，{姓名：Abhijit哥斯瓦米， 电子邮件： [e-mail]， contactNo： 9158417355， 性别： 男性}]， TOTALCOUNT：[{ 总计：192}]} 

在上面的字符串中我不想在数组中使用totalCount值。

I只想在联系人列表数组之后totalCount：192。

 {contactList：[{姓名：Abhijit Goswami，电子邮件：[e-mail]，contactNo：9158417355，性别：男性} ，{姓名：Abhijit Goswami，电子邮件：abhijitda @ facebook.com，contactNo：9158417355，性别：男性}]，totalCount：192} 

我尝试了什么：



目前是我的用于将DataSet转换为JSON字符串的代码如下所示

 ds.Tables [0] .TableName =contactList; 
 ds.Tables [1] .TableName =totalCount; 
 json = JsonConvert.SerializeObject（ds，Formatting.None）; 

解决方案

尝试这样的事情：

 json = JsonConvert.SerializeObject（ new  
 {
 contactList = ds.Tables [ 0 ]，
 totalCount = ds.Tables [ 1 ]。Rows.Cast< DataRow>（） 。选择（r = >  r [ 0 ]）。FirstOrDefault（）
}， Formatting.None）; 

Hello there's..
I want to concatenate two json string.
first string contains data tables records details and other string contains Count value.
I get that values In data set such that.

dataset ds.Tables[0]= //table records
ds.tables[1]=// singale integer value (e.g. TotalCount=12)

I convert ds in json but it return json string like.

{"contactList":[{"Name":"Abhijit Goswami","email":"[e-mail]","contactNo":"9158417355","gender":"Male"},{"Name":"Abhijit Goswami","email":"[e-mail]","contactNo":"9158417355","gender":"Male"},{"Name":"Abhijit Goswami","email":"[e-mail]","contactNo":"9158417355","gender":"Male"}],"totalCount":[{"Total":192}]}

In above string I don't want to totalCount value in array.
I just want to "totalCount:192" after the contact list array.

{"contactList":[{"Name":"Abhijit Goswami","email":"[e-mail]","contactNo":"9158417355","gender":"Male"},{"Name":"Abhijit Goswami","email":"[e-mail]","contactNo":"9158417355","gender":"Male"}],"totalCount":192}

What I have tried:

currently my code for converting DataSet to JSON string as bellow

ds.Tables[0].TableName = "contactList";
        ds.Tables[1].TableName = "totalCount";             
        json = JsonConvert.SerializeObject(ds, Formatting.None);

解决方案

Try something like this:

json = JsonConvert.SerializeObject(new 
{
    contactList = ds.Tables[0],
    totalCount = ds.Tables[1].Rows.Cast<DataRow>().Select(r => r[0]).FirstOrDefault()
}, Formatting.None);
