在 c# 中拆分字符串

Question

我有一个string被发布到我的 MVC 操作中，如下所示：

[{"property":"radius","value":"twentyfive"},{"property":"latlng","value":"40.036218,-75.51381100000003"}]

在这种情况下，我需要twentyfive的半径值，但可以是任何值，也可以是每个纬度和经度数，所以在这里它们是40.036218和-75.51381100000003 。

所以像：

string filter = "[{\"property\":\"radius\",\"value\":\"twentyfive\"},{\"property\":\"latlng\",\"value\":\"40.036218,-75.51381100000003\"}]";
string radius = //whatever i need to do;
double lat = //whatever i need to do;
double lng = //whatever i need to do;

谢谢！

您可以像这样创建 class

public class PropertyValue
{
    public string property {get; set;}
    public string value  {get; set;}
}

并使用JavaScriptSerializer

string inputString = @"[{""property"":""radius"",""value"":""twentyfive""},{""property"":""latlng"",""value"":""40.036218,-75.51381100000003""}]";
IList<PropertyValue> propertyValueList = new JavaScriptSerializer()
        .Deserialize<IList<PropertyValue>>(inputString);
Console.WriteLine(propertyValueList.Single(p  => p.property == "radius").value);
