C# C基于另一个列表字符串对类属性列表进行排序

我使用反射遍历属性列表，并将该值指定给表格单元格。正在循环的类属性被分配到错误的列标题

如何根据标题列表对数据列表属性名称进行排序？他们的名字都一样。我宁愿这样做，也不愿根据属性对标题列表进行排序

public void SetTableStrong<T>(List<T> dataList, List<string> header)
{       
    // Define our columns
    Column c = null;
    foreach (var item in header)
    {
        c = table.addTextColumn(item);
        c.horAlignment = Column.HorAlignment.CENTER;
    }

    // Initialize Your Table
    table.initialize();
    table.data.Clear();

    foreach (var item in dataList.Select((value, index) => new { value, index }))
    {
        Datum d = Datum.Body(item.index.ToString());

        //Property set to wrong header because they are not sorted to the same as headers.
        foreach (var property in item.value.GetType().GetProperties())
        {
            var value = property.GetValue(item.value, null);

            if (value == null)
                continue;

            d.elements.Add(value.ToString());
        }
        table.data.Add(d);
    }

    // Draw Your Table
    table.startRenderEngine();
}

dataList类型将始终是具有属性的类

public void SetTableStrong<T>(List<T> dataList, List<string> header)
{       
    // Define our columns
    Column c = null;
    foreach (var item in header)
    {
        c = table.addTextColumn(item);
        c.horAlignment = Column.HorAlignment.CENTER;
    }

    // Initialize Your Table
    table.initialize();
    table.data.Clear();

    foreach (var item in dataList.Select((value, index) => new { value, index }))
    {
        Datum d = Datum.Body(item.index.ToString());

        //Property set to wrong header because they are not sorted to the same as headers.
        foreach (var property in item.value.GetType().GetProperties())
        {
            var value = property.GetValue(item.value, null);

            if (value == null)
                continue;

            d.elements.Add(value.ToString());
        }
        table.data.Add(d);
    }

    // Draw Your Table
    table.startRenderEngine();
}

一种方法是首先将所有属性添加到字典中，然后循环列，并从字典中选择相应的值：

var propValueByName = item
    .value
    .GetType()
    .GetProperties()
    .Select(p => new {
        p.Name
    ,   Val = p.GetValue(item.value, null)
    }).Where(p => p.Val != null)
    .ToDictionary(p => p.Name, p => p.Val.ToString());

现在循环列，并将propValueByName[columnName]添加到d元素：

您可以缓存属性，然后按照与头相同的顺序获取它们

private static Dictionary<Type, PropertyInfo[]> TypeProperties
    = new Dictionary<Type, PropertyInfo[]>();
public IEnumerable<PropertyInfo> GetTypeProperties<T>()
{
    Type type = typeof(T);
    PropertyInfo[] properties;
    if (!TypeProperties.TryGetValue(type, out properties))
        TypeProperties.Add(type, properties = type.GetProperties());
    return properties;
}

/* Fixed excerpt from your code */

var properties = GetTypeProperties<T>();
foreach (var hdr in header)
{
    var property = properties.FirstOrDefault(p => p.PropertyName == hdr);
    if (property != null)
    {
        var value = property.GetValue(item.value, null);
        if (value==null) //Doesn't this also mess the order?
            continue;
        d.elements.Add(value.ToString());
    }
}
table.data.Add(d);

我想知道您使用的是哪种桌面软件包？@JoeBlow table Pro for Unity3D谢谢！我们曾经建造过自己的…：/
