Attributes

xref:NanoByte.CodeGeneration.CSharpAttribute can be added to types, properties and enum values. Both positional and named arguments are supported, and the Attribute suffix is stripped automatically when emitting code.

var obsolete = new CSharpAttribute(new CSharpIdentifier("System", "ObsoleteAttribute"))
{
    Arguments = {"Use NewMethod instead."},
    NamedArguments = {("DiagnosticId", "MYAPP001")}
};

myClass.Attributes.Add(obsolete);

The example above emits [Obsolete("Use NewMethod instead.", DiagnosticId = "MYAPP001")] and adds using System; to the generated file.

Argument values are written as C# literals, so strings, numbers and booleans are supported out of the box.
