Question

我有一个自定义类的列表，并希望通过属性订购此列表，但我只有属性名称的字符串，因为我从javascript中读取了这个。我用System.Reflection尝试了这个，但似乎它没有用：

Dim l As List(Of ActionElement) = New List(Of ActionElement)
'Fill the list
l = l.OrderBy(Function(x) GetType(ActionElement).GetProperty("Designation")).ToList()

Answer 1

这会让你得到你想要的东西：

Dim l As List(Of ActionElement) = New List(Of ActionElement)
'Fill the list
l = l.OrderBy(Function(x) GetType(ActionElement).GetProperty("Designation").GetValue(x).ToString()).ToList()

我会略微改变它以减少操作：

Dim l As List(Of ActionElement) = New List(Of ActionElement)
Dim sortProperty as PropertyInfo = GetType(ActionElement).GetProperty("Designation")

'Fill the list
l = l.OrderBy(Function(x) sortProperty.GetValue(x).ToString()).ToList()

VisualBasic order by Property by String
