在C# CollectionViewSource中查找记录

public class YourDataType
{
    public string PropertyName { get; set; }
    // 其他属性
}

public void FindRecord(List<YourDataType> yourDataSource, string searchValue)
{
    CollectionViewSource collectionViewSource = new CollectionViewSource();
    collectionViewSource.Source = yourDataSource;

    collectionViewSource.Filter += (sender, e) =>
    {
        var item = e.Item as YourDataType;
        if (item != null)
        {
            e.Accepted = item.PropertyName == searchValue;
        }
    };

    collectionViewSource.View.MoveCurrentToFirst();
    while (collectionViewSource.View.CurrentPosition != -1)
    {
        var currentItem = collectionViewSource.View.CurrentItem as YourDataType;
        if (currentItem != null && currentItem.PropertyName == searchValue)
        {
            // 找到记录
            Console.WriteLine("找到记录: " + currentItem.PropertyName);
            break;
        }
        collectionViewSource.View.MoveCurrentToNext();
    }
}
