首先，实现ICompare接口
public class ObjectPropertyCompare<T> : IComparer<T> { private PropertyDescriptor property; private ListSortDirection direction; // 构造函数 public ObjectPropertyCompare(PropertyDescriptor property, ListSortDirection direction) { this.property = property; this.direction = direction; } // 实现IComparer中方法 public int Compare(T x, T y) { object xValue = x.GetType().GetProperty(property.Name).GetValue(x, null); object yValue = y.GetType().GetProperty(property.Name).GetValue(y, null); int returnValue; if (xValue is IComparable) { returnValue = ((IComparable)xValue).CompareTo(yValue); } else if (xValue.Equals(yValue)) { returnValue = 0; } else { returnValue = xValue.ToString().CompareTo(yValue.ToString()); } if (direction == ListSortDirection.Ascending) { return returnValue; } else { return returnValue * -1; } }}
然后创建自定义的类，实现IBindingList接口，为方便起见，这里直接继承BindingList类
/// <summary> /// 自定义绑定列表类 /// </summary> /// <typeparam name="T">列表对象类型</typeparam> public class BindingCollection<T> : BindingList<T> { private bool isSorted; private PropertyDescriptor sortProperty; private ListSortDirection sortDirection; /// <summary> /// 构造函数 /// </summary> public BindingCollection() : base() { } /// <summary> /// 构造函数 /// </summary> /// <param name="list">IList类型的列表对象</param> public BindingCollection(IList<T> list) : base(list) { } /// <summary> /// 自定义排序操作 /// </summary> /// <param name="property"></param> /// <param name="direction"></param> protected override void ApplySortCore(PropertyDescriptor property, ListSortDirection direction) { List<T> items = this.Items as List<T>; if (items != null) { ObjectPropertyCompare<T> pc = new ObjectPropertyCompare<T>(property, direction); items.Sort(pc); isSorted = true; } else { isSorted = false; } sortProperty = property; sortDirection = direction; this.OnListChanged(new ListChangedEventArgs(ListChangedType.Reset, -1)); } /// <summary> /// 获取一个值，指示列表是否已排序 /// </summary> protected override bool IsSortedCore { get { return isSorted; } } /// <summary> /// 获取一个值，指示列表是否支持排序 /// </summary> protected override bool SupportsSortingCore { get { return true; } } /// <summary> /// 获取一个只，指定类别排序方向 /// </summary> protected override ListSortDirection SortDirectionCore { get { return sortDirection; } } /// <summary> /// 获取排序属性说明符 /// </summary> protected override PropertyDescriptor SortPropertyCore { get { return sortProperty; } } /// <summary> /// 移除默认实现的排序 /// </summary> protected override void RemoveSortCore() { isSorted = false; this.OnListChanged(new ListChangedEventArgs(ListChangedType.Reset, -1)); }
创建BindingCollection后即可直接应用：
原来的方式是：
IList<object> list = new List<object>();
...
dataGridView.DataSource = list;
现在只需更改最后一句为：
dataGridView.DataSource = new BindingCollection<object>(list);
即可
