VBCodeProvider Constructor (IDictionary<String^, String^>^)
Initializes a new instance of the VBCodeProvider class by using the specified provider options.
Assembly: System (in System.dll)
Parameters
- providerOptions
-
Type:
System.Collections.Generic::IDictionary<String^, String^>^
A IDictionary<TKey, TValue> object that contains the provider options from the configuration file.
| Exception | Condition |
|---|---|
| ArgumentNullException | providerOptions is null. |
The value for providerOptions is obtained from the element in the configuration file. You can identify the version of the VBCodeProvider you want to use by specifying the <providerOption> element, supplying "CompilerVersion" as the option name, and supplying the version number (for example, "v3.5") as the option value. You must precede the version number with a lower case "v".
The following configuration file example demonstrates how to specify that version 3.5 of the Visual Basic code provider should be used.
<configuration>
<system.codedom>
<compilers>
<!-- zero or more compiler elements -->
<compiler
language="vb;VisualBasic"
extension=".vb"
type="Microsoft.VisualBasic.VBCodeProvider, System,
Version=2.0.3600.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089"
compilerOptions="/optimize"
warningLevel="1" >
<providerOption
name="CompilerVersion"
value="v3.5" />
</compiler>
</compilers>
</system.codedom>
</configuration>
The following example shows how to specify the compiler version when creating a new instance of the VBCodeProvider class.
Imports System Imports System.CodeDom.Compiler Imports Microsoft.CSharp Imports Microsoft.VisualBasic Imports System.Collections.Generic Class Program Shared Sub Main(ByVal args() As String) DisplayVBCompilerInfo() Console.WriteLine("Press Enter key to exit.") Console.ReadLine() End Sub 'Main Shared Sub DisplayVBCompilerInfo() Dim provOptions As New Dictionary(Of String, String) provOptions.Add("CompilerVersion", "v3.5") ' Get the provider for Microsoft.VisualBasic Dim vbProvider As VBCodeProvider = New VBCodeProvider(provOptions) ' Display the Visual Basic language provider information. Console.WriteLine("Visual Basic provider is {0}", vbProvider.ToString()) Console.WriteLine(" Provider hash code: {0}", vbProvider.GetHashCode().ToString()) Console.WriteLine(" Default file extension: {0}", vbProvider.FileExtension) Console.WriteLine() End Sub 'DisplayVBCompilerInfo End Class 'Program
