的foreach到LINQ

Question

我有2個foreach循環和我試圖將其轉換成一個LINQ的：

Dim result As Type = Nothing 

For Each AssemblyItem As Reflection.Assembly In AppDomain.CurrentDomain.GetAssemblies 
    For Each typeItem As Type In AssemblyItem.GetTypes 
     If myClass.FullName = typeItem.FullName Then 
      result = typeItem 
      Exit For 
     End If 
    Next 

    If Not IsNothing(result) Then 
     Exit For 
    End If 
Next 

目前我有：

result = AppDomain.CurrentDomain.GetAssemblies() 
     .ForEach(Sub(x As Reflection.Assembly) 
        x.GetTypes().ForEach(Sub(t As Type) 
               t.FullName = catalogEntity)) 

我也試圖與另一種方法用沒有運氣：

result = AppDomain.CurrentDomain.GetAssemblies() 
     .Select(Sub(x) x.GetTypes() 
     .Select(Function(y) y.GetType()) 
     .Where(Function(z) z.FullName.Equals(catalogEntity.FullName))).FirstOrDefault() 

但我發現了以下錯誤：

Argument not specified for parameter 'action' of 'Public Shared Sub ForEach(Of T)(array() As T, action As System.Action(Of T))'

任何幫助將不勝感激，提前致謝！

這是在VB：

Dim result as Type = AppDomain.CurrentDomain.GetAssemblies().SelectMany(Function(x) x.GetTypes()).FirstOrDefault(Function(x) x.FullName Is myClass.FullName) 

而在C＃（我的母語.NET語言）：
