Then the code sets myAttribute to the value of the ReadOnlyAttribute in the AttributeCollection and checks whether the property is read-only.


// Gets the attributes for the property.
AttributeCollection attributes = 
   TypeDescriptor.GetProperties(this)["MyProperty"].Attributes;

// Checks to see whether the property is read-only.
ReadOnlyAttribute myAttribute = 
   (ReadOnlyAttribute)attributes[typeof(ReadOnlyAttribute)];

if(myAttribute.IsReadOnly) {
   // Insert code here.
}
