从GetType获取泛型类

Question

I tried to get data from database by using GetType.

Example in VB.net:

Dim genericObject = Me.UnitOfWork.GetAll(Of GetType("MyNamespace.Student"))()

For sure this code got error. But i don't have any idea to retrieve data from database by using string of class name.

My project is, i tried to create dynamic document merging.

You need to do Me.UnitOfWork.GetAll(of MyNamespace.Student)() . If the class isn't known at compile time then you'll need to invoke it via reflection

Dim method As MethodInfo = Me.UnitOfWork.GetType().GetMethod("GetAll")
Dim generic As MethodInfo = method.MakeGenericMethod(GetType("MyNamespace.Student"))
generic.Invoke(Me.UnitOfWork, Nothing)
