【问题描述】：

这是我的输入 Json：

如何获取“值”字段并将其设置为属性？

 [
        {
            "Name": "Утасны дугаар",
            "Value": "95252351",
            "ParameterName": "{xacparam01}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        },
        {
            "Name": "dans",
            "Value": "99115544",
            "ParameterName": "{xacparam02}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        },
        {
            "Name": "dfd",
            "Value": "88554455",
            "ParameterName": "{xacparam03}",
            "IsRequired": "1",
            "MinLength": "5",
            "MaxLength": "10",
            "Type": "String"
        }
    ]

当我遍历json时，我只能得到最后一次迭代

期望的输出：

{
"val1" : "95252351",
"val2" : "99115544",
"val3" : "88554455"
}

【解决方案1】：

无法为 JSON 对象生成字段名称。您可以使用给定的代理获得如下输出。

输出 JSON

{
    "values": [
        95252351,
        99115544,
        88554455
    ]
}
