Why is this an issue?
When defining custom attributes, System.AttributeUsageAttribute must be used to indicate where the attribute can be applied. This will
determine its valid locations in the code.
Noncompliant code example
using System;
namespace MyLibrary
{
public sealed class MyAttribute :Attribute // Noncompliant
{
string text;
public MyAttribute(string myText)
{
text = myText;
}
public string Text
{
get
{
return text;
}
}
}
}
Compliant solution
using System;
namespace MyLibrary
{
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Enum | AttributeTargets.Interface | AttributeTargets.Delegate)]
public sealed class MyAttribute :Attribute
{
string text;
public MyAttribute(string myText)
{
text = myText;
}
public string Text
{
get
{
return text;
}
}
}
}
