VB.NET equivalent to C#'s using directive

问题

I am converting some code from C# to VB.NET, and I need to know what the equivalent is for C#'s using directive.

Update: Sorry, but so far I haven't gotten my answer. Here is a C# example:

using moOutlook = Microsoft.Office.Interop.Outlook;
using moExcel = Microsoft.Office.Interop.Excel;

namespace ReportGen
{
    class Reports

回答1:

You're looking for the Imports statement. Place any import statements that you need at the very top of your code file, just like the using directive in C#:

Imports moOutlook = Microsoft.Office.Interop.Outlook
Imports moExcel = Microsoft.Office.Interop.Excel

Namespace ReportGen
   Public Class Reports
      'Your code here
   End Class
End Namespace

Here is a link showing a syntax comparison between C# and VB.NET side by side.

http://www.harding.edu/fmccown/vbnet_csharp_comparison.html

From the link:

Using reader As StreamReader = File.OpenText("test.txt")
  Dim line As String = reader.ReadLine()
  While Not line Is Nothing
    Console.WriteLine(line)
    line = reader.ReadLine()
  End While
End Using

Or the imports statement (from site also):

Imports System 

Namespace Hello
   Class HelloWorld 
      Overloads Shared Sub Main(ByVal args() As String) 
         Dim name As String = "VB.NET" 

         'See if an argument was passed from the command line
          If args.Length = 1 Then name = args(0) 

          Console.WriteLine("Hello, " & name & "!") 
      End Sub 
   End Class 
End Namespace

Imports moOutlook = Microsoft.Office.Interop.Outlook; 
Imports moExcel = Microsoft.Office.Interop.Excel;
