VB.NET equivalent to C#'s using directive

2019-06-17 02:33发布

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

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

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

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