推荐答案

类型名称为System.DateTime.使用此完整类型名称或添加Import System.

—SA

The type name is System.DateTime. Use this full type name or add Import System.

您的代码有点可读性.请在其上应用适当的样式，以使其读起来更好.

似乎问题出在这里:

首先导入System 命名空间.

然后，

Your code is a bit un-readble. Please apply proper style on it so that it reads better.

It seems problem is here:

First of all import System namespace.

Then,

Public Property DateTime
   Get
      Return m_DateTime
   End Get
   Set(ByVal value)
      m_DateTime = Value
   End Set
End Property

该属性未定义类型. DateTime是.net中的一种类型.因此，属性的名称应该有所不同，您需要告诉您属性的类型.例如:

The property has no type defined. DateTime is a type in .net. So the name of the property should have been something different and you need tell the type of your property. For example:

Public Property MinDateTime as DateTime
   Get
      Return m_DateTime
   End Get
   Set(ByVal value)
      m_DateTime = Value
   End Set
End Property
