示例1: CacheAttributes
private void CacheAttributes(Attribute[] attributes)
{
DataType = attributes.OfType<DataTypeAttribute>().FirstOrDefault();
Display = attributes.OfType<DisplayAttribute>().FirstOrDefault();
DisplayColumn = attributes.OfType<DisplayColumnAttribute>().FirstOrDefault();
DisplayFormat = attributes.OfType<DisplayFormatAttribute>().FirstOrDefault();
DisplayName = attributes.OfType<DisplayNameAttribute>().FirstOrDefault();
Editable = attributes.OfType<EditableAttribute>().FirstOrDefault();
#if false
HiddenInput = attributes.OfType<HiddenInputAttribute>().FirstOrDefault();
#endif
ReadOnly = attributes.OfType<ReadOnlyAttribute>().FirstOrDefault();
Required = attributes.OfType<RequiredAttribute>().FirstOrDefault();
ScaffoldColumn = attributes.OfType<ScaffoldColumnAttribute>().FirstOrDefault();
var uiHintAttributes = attributes.OfType<UIHintAttribute>();
// Developer note: this loop is explicitly unrolled because Linq lambdas methods are not
// [SecuritySafeCritical] and generate security exceptions accessing DataAnnotations types.
UIHintAttribute bestUIHint = null;
foreach (UIHintAttribute uiHintAttribute in uiHintAttributes)
{
string presentationLayer = uiHintAttribute.PresentationLayer;
if (String.Equals(presentationLayer, "MVC", StringComparison.OrdinalIgnoreCase))
{

break;
}
if (bestUIHint == null && String.IsNullOrEmpty(presentationLayer))
{
bestUIHint = uiHintAttribute;
}
}
UIHint = bestUIHint;
if (DisplayFormat == null && DataType != null)
{
DisplayFormat = DataType.DisplayFormat;
}
