CompilerResults Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Represents the results of compilation that are returned from a compiler.

Namespace:   System.CodeDom.Compiler
Assembly:  System (in System.dll)

[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]
public class CompilerResults


Initializes a new instance of the CompilerResults class that uses the specified temporary files.


Gets or sets the compiled assembly.


Gets the collection of compiler errors and warnings.


Obsolete. Indicates the evidence object that represents the security policy permissions of the compiled assembly.


Gets or sets the compiler's return value.


Gets the compiler output messages.


Gets or sets the path of the compiled assembly.


Gets or sets the temporary file collection to use.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

This class contains the following information about the results of a compilation by an ICodeCompiler interface implementation:

  • The CompiledAssembly property indicates the compiled assembly.

  • The Evidence property indicates the security evidence for the assembly.

  • The PathToAssembly property indicates the path to the compiled assembly, if it was not generated only in memory.

  • The Errors property indicates any compiler errors and warnings.

  • The Output property contains the compiler output messages.

  • The NativeCompilerReturnValue property indicates result code value returned by the compiler.

  • The TempFiles property indicates the temporary files generated during compilation and linking.


This class contains an inheritance demand at the class level that applies to all members. A SecurityException is thrown when the derived class does not have full-trust permission. For details about inheritance demands, see Inheritance Demands.
