示例1: ToString
//引入命名空间
using System;
using System.Collections.Generic;
// Simple business object. A PartId is used to identify the type of part
// but the part name can change.
public class Part : IEquatable<Part>
{
public string PartName { get; set; }
public int PartId { get; set; }
public override string ToString()
{
return "ID: " + PartId + " Name: " + PartName;
}
public override bool Equals(object obj)
{
if (obj == null) return false;
Part objAsPart = obj as Part;
if (objAsPart == null) return false;
else return Equals(objAsPart);
}
public override int GetHashCode()
{
return PartId;
}
public bool Equals(Part other)
{
if (other == null) return false;
return (this.PartId.Equals(other.PartId));
}
// Should also override == and != operators.
}
public class Example
{
public static void Main()
{
// Create a list of parts.
List<Part> parts = new List<Part>();
// Add parts to the list.
parts.Add(new Part() {PartName="crank arm", PartId=1234});
parts.Add(new Part() { PartName = "chain ring", PartId = 1334 });
parts.Add(new Part() { PartName = "regular seat", PartId = 1434 });
parts.Add(new Part() { PartName = "banana seat", PartId = 1444 });
parts.Add(new Part() { PartName = "cassette", PartId = 1534 });
parts.Add(new Part() { PartName = "shift lever", PartId = 1634 });
// Write out the parts in the list. This will call the overridden ToString method
// in the Part class.
Console.WriteLine();
foreach (Part aPart in parts)
{
Console.WriteLine(aPart);
}
// Check the list for part #1734. This calls the IEquatable.Equals method
// of the Part class, which checks the PartId for equality.
Console.WriteLine("\nContains(\"1734\"): {0}",
parts.Contains(new Part {PartId=1734, PartName="" }));
// Insert a new item at position 2.
Console.WriteLine("\nInsert(2, \"1834\")");
parts.Insert(2, new Part() { PartName = "brake lever", PartId = 1834 });
//Console.WriteLine();
foreach (Part aPart in parts)
{
Console.WriteLine(aPart);
}
Console.WriteLine("\nParts[3]: {0}", parts[3]);
Console.WriteLine("\nRemove(\"1534\")");
// This will remove part 1534 even though the PartName is different,
// because the Equals method only checks PartId for equality.
parts.Remove(new Part(){PartId=1534, PartName="cogs"});
Console.WriteLine();
foreach (Part aPart in parts)
{
Console.WriteLine(aPart);
}
Console.WriteLine("\nRemoveAt(3)");
// This will remove the part at index 3.
parts.RemoveAt(3);
Console.WriteLine();
foreach (Part aPart in parts)
{
Console.WriteLine(aPart);
