Is there a way for me to access a C# class attribute?
For instance, if I have the following class:
...
[TableName("my_table_name")]
public class MyClass
{
...
}
Can I do something like:
MyClass.Attribute.TableName => my_table_name
Thanks!
You can use Attribute.GetCustomAttribute
method for that:
var tableNameAttribute = (TableNameAttribute)Attribute.GetCustomAttribute(
typeof(MyClass), typeof(TableNameAttribute), true);
However this is too verbose for my taste, and you can really make your life much easier by the following little extension method:
public static class AttributeUtils
{
public static TAttribute GetAttribute<TAttribute>(this Type type, bool inherit = true) where TAttribute : Attribute
{
return (TAttribute)Attribute.GetCustomAttribute(type, typeof(TAttribute), inherit);
}
}
so you can use simply
var tableNameAttribute = typeof(MyClass).GetAttribute<TableNameAttribute>();
