它更快的List.Remove（T）或.NET集合List.RemoveAt（int）方法？这是一个速度值类型和引用类型不同？

Is it faster the List.Remove(T) or List.RemoveAt(int) method in .NET collections? Is speed different for value types or reference types?

谢谢

推荐答案

List.Remove（T）使用的IndexOf和RemoveAt（INT）在其实施。所以List.RemoveAt（INT）更快。

List.Remove(T) uses IndexOf and RemoveAt(int) in its implementation. So List.RemoveAt(int) is faster.

public bool Remove(T item)
{
    int index = this.IndexOf(item);
    if (index >= 0)
    {
        this.RemoveAt(index);
        return true;
    }
    return false;
}
