我对VB.NET上的课程(以及一般的整个OOP概念)有点新意,所以很抱歉提前做了不好的解释。 我创建了一个类似的类:
Public Class MyApp
private var1 as integer = 2
Private Function getProfile(id As Integer)
'Imaginary server request according to ID
'Following that was received:
Dim name As String = "John"
Dim age As integer = 30
End Function
End Class
我希望能够通过使用myApp.getProfile调用getProfile,这是我可以处理的。 我无法管理的只显示年龄或姓名。 像这样:
MyApp.getProfile(4341).age
我怎样才能实现这样的目标?就像在函数中使用子函数一样。

要以这种方式调用方法,它需要是静态的(标记为Shared
)和公共。要使其返回名称和年龄作为属性,您需要具有这些属性的类。例如:
Public Class MyApp
Public Shared Function GetProfile(id As Integer)
Dim name As String = "John"
Dim age As integer = 30
return New ServerResult(name, age)
End Function
End Class
Public Class ServerResult
Public Name as String
Public Age as Integer
Public Sub New(n as String, a as Integer)
Name = n
age = a
End Sub
End Class
用法示例:
Dim age as Integer = MyApp.GetProfile(42).Age
另:
Dim result As ServerResult = MyApp.GetProfile(1337)
Dim info As String = String.Format("{0}, {1}", result.Name, result.Age)
注意:使方法静态取决于您想要如何调用它。您可能想要创建MyApp
类的实例,并且有一个非静态的方法。
