推荐答案

尝试一下:

try this:

Private emp As Employee
emp = New Employee( txtname.Text, txtsalary.Text)

您没有获得3个论点的承包商！

您还可以添加到承包商中:

you dont have a constractor that get 3 arguments!

you can also add to your constractor:

Sub New(ByVal  id1 as Decimal, ByVal name1 As String, ByVal salary1 As Decimal)

        name = name1
        salary = salary1
        id=id1
  End Sub

非常简单.尝试以下代码:

It''s Very Simple.Try this code :

'If Employee is the Class
Dim Employee1 As Employee = New Employee("Name","Salary")
Dim EmployeeList As List(Of Employee)
EmployeeList.Add(Employee1)
