如何避免频繁创建临时对象
1.可以使用Tuple
2.自定义元祖类
[Serializable] public class Tuple<T1, T2> : IStructuralEquatable, IStructuralComparable, IComparable, ITuple { // Fields private T1 m_Item1; private T2 m_Item2; // Methods public Tuple(T1 item1, T2 item2) { this.m_Item1 = item1; this.m_Item2 = item2; } string ITuple.ToString(StringBuilder sb) { sb.Append(this.m_Item1); sb.Append(", "); sb.Append(this.m_Item2); sb.Append(")"); return sb.ToString(); } int ITuple.Size { get { return 2; } } // Properties public T1 Item1 { get { return this.m_Item1; } } public T2 Item2 { get { return this.m_Item2; } } //More and more... }
