14.15 C#-Specific Metadata Directives

The slice2cs compiler supports metadata directives that allow you inject C# attribute specifications into the generated code. The metadata directive is cs:attribute:. For example:

["cs:attribute:System.Serializable"]
struct Point {
    double x;
    double y;
};

This results in the following code being generated for S:

[System.Serializable]
public struct Point
{
    public double x;
    public double y;
    // ...
}

You can apply this metadata directive to any slice construct, such as structure, operation, or parameter definitions.

You can use this directive also at global level. For example:

[["cs:attribute:assembly: AssemblyDescription(\"My assembly\")"]]

This results in the following code being inserted following any using directives and preceding any definitions:

[assembly: AssemblyDescription("My assembly")]
