VCCLCompilerTool.AdditionalOptions Property

Definition

Namespace:

Microsoft.VisualStudio.VCProjectEngine

Assembly:

Microsoft.VisualStudio.VCProjectEngine.dll

Package:

Microsoft.VisualStudio.VCProjectEngine v17.11.40252

Gets or sets options to add to the end of the command line immediately before the file name(s). An example is if an option is not supported in the object model.

public:
 property System::String ^ AdditionalOptions { System::String ^ get(); void set(System::String ^ value); };

public:
 property Platform::String ^ AdditionalOptions { Platform::String ^ get(); void set(Platform::String ^ value); };

[System.Runtime.InteropServices.DispId(1)]
public string AdditionalOptions { [System.Runtime.InteropServices.DispId(1)] get; [System.Runtime.InteropServices.DispId(1)] set; }

[<System.Runtime.InteropServices.DispId(1)>]
[<get: System.Runtime.InteropServices.DispId(1)>]
[<set: System.Runtime.InteropServices.DispId(1)>]
member this.AdditionalOptions : string with get, set

Public Property AdditionalOptions As String

Property Value

String

Options added to the end of the command line immediately before the file name(s)

Attributes

DispIdAttribute

Examples

The following example demonstrates how to use the EnablePREfast and AdditionalOptions properties to set the /analyze:WX- switch. (Both properties are required to do this.) Specifying /analyze:WX- means that code analysis warnings will not be treated as errors when compiling with /WX. For more information, see /analyze (Code Analysis).
