比较列表中除您自己之外的项目

我想比较列表中的项目，但不希望将其与其自身进行比较。我怎么做？ 我的代码：

var students = new List<Student>() {
                new Student(){ Id = 1, Name="Bill"},
                new Student(){ Id = 2, Name="Steve"},
                new Student(){ Id = 3, Name="Ram"},
            };

for (int i=0; i<students.Count(); i++)
{
    for (int x = 0; x < students.Count(); x++)
    {
        Console.WriteLine(students[i].Name + "   --   " + students[x].Name);
    }
}

该代码返回...

Bill   --   Bill
Bill   --   Steve
Bill   --   Ram

Steve   --   Bill
Steve   --   Steve
Steve   --   Ram

Ram   --   Bill
Ram   --   Steve
Ram   --   Ram

也许你想要这个：

var students = new List<Student>() {
                new Student(){ Id = 1, Name="Bill"},
                new Student(){ Id = 2, Name="Steve"},
                new Student(){ Id = 3, Name="Ram"},
            };

for (int i=0; i<students.Count(); i++)
{
    for (int x = 0; x < students.Count(); x++)
    {
        if(students[i].Id != students[x].Id)
        {
             Console.WriteLine(students[i].Name + "   --   " + students[x].Name);
        }
    }
}

然后你会得到：

Bill   --   Steve
Bill   --   Ram

Steve   --   Bill
Steve   --   Ram

Ram   --   Bill
Ram   --   Steve
