VB.NET相当于这个C#代码？
ctx.Load(site,x => x.Lists.Where(l => l.Title != null));
我试过了
ctx.Load(site,Function(x) x.Lists.Where(Function(l) l.Title IsNot Nothing))
但不支持“表达式(转换(l.Title)！= null)的错误.”
思考
如果Title是字符串,请尝试使用IsNullOrEmpty();
要么
Nullable(Of T).HalValue如果Title可以为Nullable
要么
Sub Main()
Dim list As New List(Of A)
Dim a1 As New A
a1.Title = "sqws"
Dim a2 As New A
a2.Title = Nothing
list.Add(a1)
list.Add(a2)
Dim q = From c In list Where c.Title IsNot Nothing
End Sub
Public Class A
Dim t As String
Public Property Title() As String
Get
Title = t
End Get
Set(ByVal value As String)
t = value
End Set
End Property
End Class
