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...
