如何在 C# 中將列表轉換為 JSON？

Question

我有一個 City_State 列表：

City_State[0].Range="\"city\":\"REDMOND\",\"state\":\"AK\"";
City_State[1].Range="\"city\":\"Alex City\",\"state\":\"

如何將其轉換為json，如下所示：

var _pairs = new
{
    criteria = new { cities = new[] { new { city = "REDMOND", state = "WA" }, 
     new { city = "Alex City", state = "AL" } } 
} ;

我嘗試了下面的代碼，但它不起作用：

var _pairs = new { criteria = new { cities = new[] { _paged_City_State.ToArray() } }  };

如果你有這些課程：

public class CityStateRaw
{
    public string Range { get; set; }
}

public class CityState
{
    public string City { get; set; }
    public string State { get; set; }
}

以下代碼將起作用：

var ranges = new[]
{
    new CityStateRaw { Range = "{\"city\":\"REDMOND\",\"state\":\"AK\"}" },
    new CityStateRaw { Range = "{\"city\":\"Alex City\",\"state\":\"foo\"}" },
};

var list = ranges
    .Select(raw => JsonConvert.DeserializeObject<CityState>(raw.Range))
    .ToList();

但是，如果這與您的期望不符，您應該更具體地說明您的確切輸入和預期輸出應該是什么。
