C#中List<T>排序

首先，List中T的定義如下：

/// <summary>
    /// GeoJSON格式的參數
    /// </summary>
    public class BodyParamShapeDistance
    {
        /// <summary>
        /// 幾何對象
        /// </summary>
        [Newtonsoft.Json.JsonProperty("Shape")]
        public GeoJSON.Net.Geometry.IGeometryObject Shape { get; set; }

        /// <summary>
        /// 距離
        /// </summary>
        [Newtonsoft.Json.JsonProperty("Distance")]
        public double Distance { get; set; }
    }
           

我們定義一個List<T>：

List<BodyParamShapeDistance> lsResult = new List<BodyParamShapeDistance>() { };
           

并對進進行指派（代碼省略）。

然後，按照其Distance進行排序：

lsResult.OrderBy((e1) => { return System.Convert.ToDouble(e1.Distance); }).ToList()
           

結果如下：

            "coordinates": [
