VB.NET如何将多字段列表（T）转换为字符串二维数组

Question

列表（T）有n列m列： 名字，姓氏，年龄.....

我想（的T）的列表转换为字符串的二维数组大小m * n个

Answer 1

我会很高兴，如果我将已经拥有的所有有意义的属性，而不是一个强类型列表一个二维数组。但是，你可能使用反射：

Dim userType As Type = GetType(User) ' User is the type of your class ' 
Dim allPublicProperties = userType.GetProperties(BindingFlags.Instance Or BindingFlags.Public) 
Dim allUserProperties(userList.Count - 1, allPublicProperties.Length - 1) As Object 
For i As Int32 = 0 To userList.Count - 1 ' userList is your List(Of User) ' 
    Dim user = userList(i) 
    For ii As Int32 = 0 To allPublicProperties.Length - 1 
     Dim userProp = allPublicProperties(ii) 
     allUserProperties(i, ii) = userProp.GetValue(user, Nothing) 
    Next
