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"}]}
