示例1: DecodeAttributeUsageAttribute
// Process the specified AttributeUsage attribute on the given ownerSymbol
private AttributeUsageInfo DecodeAttributeUsageAttribute(CSharpAttributeData attribute, AttributeSyntax node, bool diagnose, DiagnosticBag diagnosticsOpt = null)
{
Debug.Assert(diagnose == (diagnosticsOpt != null));
Debug.Assert(!attribute.HasErrors);
Debug.Assert(!this.IsErrorType());
// AttributeUsage can only be specified for attribute classes
if (!this.DeclaringCompilation.IsAttributeType(this))
{
if (diagnose)
{
diagnosticsOpt.Add(ErrorCode.ERR_AttributeUsageOnNonAttributeClass, node.Name.Location, node.GetErrorDisplayName());
}
return AttributeUsageInfo.Null;
}
else
{
AttributeUsageInfo info = attribute.DecodeAttributeUsageAttribute();
// Validate first ctor argument for AtributeUsage specification is a valid AttributeTargets enum member
if (!info.HasValidAttributeTargets)
{
if (diagnose)
{

CSharpSyntaxNode attributeArgumentSyntax = attribute.GetAttributeArgumentSyntax(0, node);
diagnosticsOpt.Add(ErrorCode.ERR_InvalidAttributeArgument, attributeArgumentSyntax.Location, node.GetErrorDisplayName());
