C# 去除json字符串key引号

采用正则表达式去除；

方法

        /// <summary>

        /// 去除json key双引号

        /// </summary>

        /// <param name="jsonInput">json</param>

        /// <returns>去除key引号</returns>

        public string JsonRegex(string jsonInput)

        {

            string result=string.Empty;

            try

            {

                string pattern = "\"(\\w+)\"(\\s*:\\s*)";

                string replacement = "$1$2";

                System.Text.RegularExpressions.Regex rgx = new System.Text.RegularExpressions.Regex(pattern);

                result = rgx.Replace(jsonInput, replacement);

            }

            catch (Exception ex)

            {

                result = jsonInput;

            }

            return result;

        }

测试案例：

json:{"action_r": [{"spr": "1", "mas": "21", "mgt": "入职"}, {"spr": "1", "mas": "22", "mgt": "转岗"}]}

public string PA_Test()

{

    string str = "{\"action_r\": [{\"spr\": \"1\", \"mas\": \"21\", \"mgt\": \"入职\"}, {\"spr\": \"1\", \"mas\": \"22\", \"mgt\": \"转岗\"}]}";

    str = this.JsonRegex(str);

    return str;

}

返回结果：

{action_r: [{spr: "1", mas: "21", mgt: "入职"}, {spr: "1", mas: "22", mgt: "转岗"}]}
