c# – 将列表转换为列表

发布时间：2020-12-16 01:54:48 所属栏目：百科来源：网络整理

导读：我有一个双打列表列表 double []我想将其转换为List T其中T是一个类. double数组包含17个值,例如[1.0,2.0,3.0,4.0,5.0,.. 17.0]. 然后我有一个类定义了17个字符串属性,例如P1,P2,….,P17 所以列表的每个元素 double []是一个双精度数组,数组中的每个元素表示

我有一个双打列表列表< double []>我想将其转换为List< T>其中T是一个类.

double数组包含17个值,例如[1.0,2.0,3.0,4.0,5.0,.. 17.0].
然后我有一个类定义了17个字符串属性,例如P1,P2,….,P17

所以列表的每个元素< double []>是一个双精度数组,数组中的每个元素表示类型为T的类中的属性值.

是否可以将给定的双精度数组的每个索引映射到类型为T的类的属性.所以我转换一个List< double []>列出< T> T是班级.

我知道可以通过手动迭代读取每个数组的列表来完成
从数组的每个索引读取值并将其传递给类的相应属性.
但是当我有很多10个属性的课时,它有很多工作要做.

编辑：下面给出了其中一个类的示例

/// <summary>
/// Defines the properties of a centroid.
/// </summary>
public class Centroid
{
    // ReSharper disable InconsistentNaming
    /// <summary>
    /// Calls made to contacts
    /// </summary>
    public string CONTACT_CALLS { get; set; }

    /// <summary>
    /// Duration of calls made to contacts
    /// </summary>
    public string CONTACT_CALLS_SEC { get; set; }

    /// <summary>
    /// Calls made to non contacts
    /// </summary>      
    public string UNKNOWN_CALLS { get; set; }

    /// <summary>
    /// Duration of calls made to non contacts
    /// </summary>
    public string UNKNOWN_CALLS_SEC { get; set; }

    /// <summary>
    /// Number of SMS sent to contacts
    /// </summary>
    public string SMS_OUT_CONTACTS { get; set; }

    /// <summary>
    /// Number of SMS sent to non contacts
    /// </summary>
    public string SMS_OUT_UNKNOWN { get; set; }

    /// <summary>
    /// Percentage of CPU usaed
    /// </summary>
    public string CPU_USAGE { get; set; }

    /// <summary>
    /// Percentage of RAM used
    /// </summary>
    public string RAM_USAGE { get; set; }

    /// <summary>
    /// Number of system application
    /// </summary>
    public string SYS_APPS { get; set; }

    /// <summary>
    /// Number of user applications
    /// </summary>
    public string USER_APPS { get; set; }

    /// <summary>
    /// Number of system services
    /// </summary>
    public string SYS_SERVICES { get; set; }

    /// <summary>
    /// Number of user services
    /// </summary>
    public string USER_SERVICES { get; set; }

    /// <summary>
    /// Number of bytes sent
    /// </summary>
    public string BYTES_TX { get; set; }

    /// <summary>
    /// Number of bytes received
    /// </summary>
    public string BYTES_RX { get; set; }

    /// <summary>
    /// Latitute of the location
    /// </summary>
    public string LOC_LAT { get; set; }

    /// <summary>
    /// Longitude of the location
    /// </summary>
    public string LOC_LON { get; set; }

    /// <summary>
    /// The Time Slice
    /// </summary>
    public string TIME_SLICE { get; set; }

    // ReSharper restore InconsistentNaming
}

EDIT2：从列表创建列表的方法,注意_profiler.FinalCentroid的类型为List< double []>

private void CreateListOfCentroids()
    {
        _centroidsList = new CentroidsList {Centroids = new List<Centroid>()};

        foreach (var centroid in _profiler.FinalCentroid.Select(doublese => new Centroid
        {
            CONTACT_CALLS = doublese[0].ToString(CultureInfo.InvariantCulture),CONTACT_CALLS_SEC = doublese[1].ToString(CultureInfo.InvariantCulture),UNKNOWN_CALLS = doublese[2].ToString(CultureInfo.InvariantCulture),UNKNOWN_CALLS_SEC = doublese[3].ToString(CultureInfo.InvariantCulture),SMS_OUT_CONTACTS = doublese[4].ToString(CultureInfo.InvariantCulture),SMS_OUT_UNKNOWN = doublese[5].ToString(CultureInfo.InvariantCulture),CPU_USAGE = doublese[6].ToString(CultureInfo.InvariantCulture),RAM_USAGE = doublese[7].ToString(CultureInfo.InvariantCulture),SYS_APPS = doublese[8].ToString(CultureInfo.InvariantCulture),USER_APPS = doublese[9].ToString(CultureInfo.InvariantCulture),SYS_SERVICES = doublese[10].ToString(CultureInfo.InvariantCulture),USER_SERVICES = doublese[11].ToString(CultureInfo.InvariantCulture),BYTES_TX = doublese[12].ToString(CultureInfo.InvariantCulture),BYTES_RX = doublese[13].ToString(CultureInfo.InvariantCulture),LOC_LAT = doublese[14].ToString(CultureInfo.InvariantCulture),LOC_LON = doublese[15].ToString(CultureInfo.InvariantCulture),TIME_SLICE = doublese[16].ToString(CultureInfo.InvariantCulture)
        }))
        {
            _centroidsList.Centroids.Add(centroid);
        }
    }//end method

解决方法

要发布明显的,为什么不在构造函数中分配属性？
您将开始创建属性的工作.
在构造函数中分配值的键击次数少于属性.

List<double[]> ld = new List<double[]>();
List<PropDouble> lpd = new List<PropDouble>();
foreach (double[] da in ld) { lpd.Add(new PropDouble(da)); }

public class PropDouble
{
    public double P0 { get; set; }
    public double P1 { get; set; }
    public PropDouble(double[] doubles) { P0 = doubles[0]; P1 = doubles[1]; }
}

要么

public class PropDouble
{
    private double[] doubles;
    public double P0 { get { return doubles[0]; } set { doubles[0] = value; } }
    public double P1 { get { return doubles[1]; } set { doubles[1] = value; } }
    public PropDouble(double[] Doubles) { doubles = Doubles; }
}
