如何检查类对象中的重复项

问题描述

需要检查对象属性中是否有重复项。

ex：

need to check if any duplicates in an object properties.
ex:

class Emp{
public string id;
public string Ename;
public string Eadd;
SVM()
{
Emp emp = new Emp(){id=1,Ename="raja",Eadd="1"};
}

现在id和eadd包含重复项，



如何检查重复项。

request:please try to understand ,instead reject any other un useful comments.

推荐答案

public bool hasDuplicates()
{
  bool has_dup = false;
  if ( id == Ename || id == Eadd || Eadd == Ename) has_dup = true;
  return has_dup;
}

class Emp
{
    public string id;
    public string Ename;
    public string Eadd;

    public bool HasDuplicates
    {
        get
        {
            if (id == Ename || id == Eadd)
            {
                return true;
            }

            if (Ename == Eadd)
            {
                return true;
            }

            return false;
        }
    }
}

使用

usage

Emp e1 = new Emp { id = "1", Ename = "raja", Eadd = "1" };
Console.WriteLine(e1.HasDuplicates);

Emp e2 = new Emp { id = "2", Ename = "raja", Eadd = "3" };
Console.WriteLine(e2.HasDuplicates);

Emp e3 = new Emp { id = "3", Ename = "raja", Eadd = "raja" };
Console.WriteLine(e3.HasDuplicates);
