CSharpCodeProvider Class
Assembly: System (in system.dll)
This class provides methods that can be used to retrieve instances of the C# ICodeGenerator and ICodeCompiler implementations.
The following example uses either the C# or Visual Basic code provider to compile a source file. The example checks the input file extension and uses the corresponding CSharpCodeProvider or VBCodeProvider for compilation. The input file is compiled into an executable file, and any compilation errors are displayed to the console.
Public Shared Function CompileExecutable(sourceName As String) As Boolean Dim sourceFile As FileInfo = New FileInfo(sourceName) Dim provider As CodeDomProvider = Nothing Dim compileOk As Boolean = False ' Select the code provider based on the input file extension. If sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) = ".CS" provider = New Microsoft.CSharp.CSharpCodeProvider() ElseIf sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) = ".VB" provider = New Microsoft.VisualBasic.VBCodeProvider() Else Console.WriteLine("Source file must have a .cs or .vb extension") End If If Not provider Is Nothing ' Format the executable file name. ' Build the output assembly path using the current directory ' and <source>_cs.exe or <source>_vb.exe. Dim exeName As String = String.Format("{0}\{1}.exe", _ System.Environment.CurrentDirectory, _ sourceFile.Name.Replace(".", "_")) Dim cp As CompilerParameters = new CompilerParameters() ' Generate an executable instead of ' a class library. cp.GenerateExecutable = True ' Specify the assembly file name to generate. cp.OutputAssembly = exeName ' Save the assembly as a physical file. cp.GenerateInMemory = False ' Set whether to treat all warnings as errors. cp.TreatWarningsAsErrors = False ' Invoke compilation of the source file. Dim cr As CompilerResults = provider.CompileAssemblyFromFile(cp, _ sourceName) If cr.Errors.Count > 0 ' Display compilation errors. Console.WriteLine("Errors building {0} into {1}", _ sourceName, cr.PathToAssembly) Dim ce As CompilerError For Each ce In cr.Errors Console.WriteLine(" {0}", ce.ToString()) Console.WriteLine() Next ce Else ' Display a successful compilation message. Console.WriteLine("Source {0} built into {1} successfully.", _ sourceName, cr.PathToAssembly) End If ' Return the results of the compilation. If cr.Errors.Count > 0 compileOk = False Else compileOk = True End If End If return compileOk End Function
