如何去掉Json字符串中反斜杠

做项目的时候，遇到了这样的问题，前台传来的Json字符串在实体类中不对应（无法转换为实体类），而且传来的数据项是跟着数据库中的表的变动而变动的（不能重写实体类）。

前台Json字符串为：

string s1 ="[{"ID":"99d2a341-ea2e-4f04-b4f4-623153d64336","Name":"王五","TotalScores":80,"工作效率":"B","职业道德":"B","业务能力":"A","链接自律":"B","工作成绩":"B"},{"ID":"728f72ac-473b-4bde-bf83-7ed93d3fd9e6","Name":"李四","TotalScores":80,"工作效率":"B","职业道德":"B","业务能力":"A","链接自律":"B","工作成绩":"B"},{"ID":"29c80443-d0ac-414c-91b5-acd5e69e28f2","Name":"刘七","TotalScores":80,"工作效率":"B","职业道德":"B","业务能力":"A","链接自律":"B","工作成绩":"B"}]";

可以看到其实在微软中将““”作为双引号用的，思路是这样的：

1、去掉““”

代码实现：

            strings11=s1.Replace(""","");

2、去掉”[]“

代码实现：

            string s22 =s11.Replace("[","");

            string s33 =s22.Replace("]", "");

这是时候我们得到的s33是这样的:

s33="{ID:99d2a341-ea2e-4f04-b4f4-623153d64336,Name:王五,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B},{ID:728f72ac-473b-4bde-bf83-7ed93d3fd9e6,Name:李四,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B},{ID:29c80443-d0ac-414c-91b5-acd5e69e28f2,Name:刘七,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B}"

3、将”}，{“调换为”}“，去掉空值

代码实现：

string s44 =s33.Replace("},{","}");

s44="{ID:99d2a341-ea2e-4f04-b4f4-623153d64336,Name:王五,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B}ID:728f72ac-473b-4bde-bf83-7ed93d3fd9e6,Name:李四,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B}ID:29c80443-d0ac-414c-91b5-acd5e69e28f2,Name:刘七,TotalScores:80,工作效率:B,职业道德:B,业务能力:A,链接自律:B,工作成绩:B}"

string[] s55s =s44.Split(new Char[] { '}', '{' }, StringSplitOptions.RemoveEmptyEntries);

s55s是得到的”ID：99d2a341-ea2e-4f04-b4f4-623153d64336，Name:王五，...“将得到的结果放在字典中：

<span style="font-size:18px;"><span style="font-size:18px;">  for (int i = 0; i < updatedEdit.Length; i++) {
                    //string[] detailevaluationinfo = updatedEdit[i].Split(',');
                    string pat = @"(?<key>[^,:s]*):(?<value>[^,:s]*)";
                    //一组之间的数据拿出来
                    //for (int j = 0; j < detailevaluationinfo.Length; j++) {
                    MatchCollection matches = Regex.Matches(updatedEdit[i], pat);
                        Dictionary<string, string> dict = new Dictionary<string, string>();
                        foreach (Match m in matches)
                        {
                            if (dict.ContainsKey(m.Groups["key"].Value)) continue;//不能重复啊
                            dict.Add(m.Groups["key"].Value, m.Groups["value"].Value);
                        }

}</span></span>

<span style="font-size:18px;"><span style="font-size:18px;">  for (int i = 0; i < updatedEdit.Length; i++) {
                    //string[] detailevaluationinfo = updatedEdit[i].Split(',');
                    string pat = @"(?<key>[^,:s]*):(?<value>[^,:s]*)";
                    //一组之间的数据拿出来
                    //for (int j = 0; j < detailevaluationinfo.Length; j++) {
                    MatchCollection matches = Regex.Matches(updatedEdit[i], pat);
                        Dictionary<string, string> dict = new Dictionary<string, string>();
                        foreach (Match m in matches)
                        {
                            if (dict.ContainsKey(m.Groups["key"].Value)) continue;//不能重复啊
                            dict.Add(m.Groups["key"].Value, m.Groups["value"].Value);
                        }
}</span></span>

这样就可以将Json字符串截取出来。
