CodeDomProvider.CompileAssemblyFromFile(CompilerParameters, String[]) Method


Compiles an assembly from the source code contained in the specified files, using the specified compiler settings.

 virtual System::CodeDom::Compiler::CompilerResults ^ CompileAssemblyFromFile(System::CodeDom::Compiler::CompilerParameters ^ options, ... cli::array <System::String ^> ^ fileNames);
public virtual System.CodeDom.Compiler.CompilerResults CompileAssemblyFromFile (System.CodeDom.Compiler.CompilerParameters options, params string[] fileNames);
abstract member CompileAssemblyFromFile : System.CodeDom.Compiler.CompilerParameters * string[] -> System.CodeDom.Compiler.CompilerResults
override this.CompileAssemblyFromFile : System.CodeDom.Compiler.CompilerParameters * string[] -> System.CodeDom.Compiler.CompilerResults
Public Overridable Function CompileAssemblyFromFile (options As CompilerParameters, ParamArray fileNames As String()) As CompilerResults



A CompilerParameters object that indicates the settings for the compilation.


An array of the names of the files to compile.


A CompilerResults object that indicates the results of compilation.


Neither this method nor the CreateCompiler() method is overridden in a derived class.

.NET Core and .NET 5+ only: In all cases.



In the .NET Framework versions 1.0 and 1.1, this method is provided by the ICodeCompiler implementation that is returned by the CreateCompiler method of the provider. In version 2.0, this method can be called directly on the code provider even if it is not overridden by the code provider. If the code provider does not override this method, the ICodeCompiler implementation is called by the base class.


On .NET Core and .NET 5+, calls to the CodeDomProvider.CompileAssemblyFromFile method throw a PlatformNotSupportedException. Compile from file is not supported.

Notes to Inheritors

If you override this method, you must not call the corresponding method of the base class. The base-class method creates a generator in the derived class using the obsolete CreateCompiler() method for compatibility with preexisting providers that use code compilers. The base-class method then calls the equivalent method in the ICodeCompiler implementation to perform this function. You will get a NotImplementedException if you call the base-class method from a code provider that does not use a code compiler.
