PersonInfo类：
public class PersonInfo
{
public int Index;
public string Name; public override string ToString()
{
return string.Format("Index:{0}, Name:{1}", Index, Name);
}
}
PersonInfoCompareByName比较类：
public class PersonInfoCompareByName : IEqualityComparer<PersonInfo>
{
public bool Equals(PersonInfo x, PersonInfo y)
{
if (x != null && y != null && x.Name == y.Name)
return true; return false;
} public int GetHashCode(PersonInfo obj)
{
if (obj == null)
{
return ;
}
else
{
return obj.Name.GetHashCode();
}
}
}
下面的代码是新建一个列表，然后去除重复项：
private void Button_Click(object sender, RoutedEventArgs e)
{
List<PersonInfo> PersonList = new List<PersonInfo>();
for (int i = ; i < ; i++)
{
for (int j = ; j < ; j++)
{
var info = new PersonInfo();
info.Index = j;
info.Name = "Name" + i;
PersonList.Add(info);
}
} var items = PersonList.Distinct(new PersonInfoCompareByName());
foreach (var item in items)
{
Console.WriteLine(item.ToString());
}
}
