.Net2.0中的数组类型转换
做DesignLibrary.需要进行大量的数组类型转换，因此得写大量自定义方法，实在累人。
Baidu一下，发现新大陆。又是泛型，真是神奇，原来2.0给我们准备了这么多泛型方法。
//
// Summary:
// Converts an array of one type to an array of another type.
//
// Parameters:
// array:
// The one-dimensional, zero-based System.Array to convert to a target type.
//
// converter:
// A System.Converter<TInput,TOutput> that converts each element from one type
// to another type.
//
// Returns:
// An array of the target type containing the converted elements from the source
// array.
//
// Exceptions:
// System.ArgumentNullException:
// array is null.-or-converter is null.
public static TOutput[] ConvertAll < TInput, TOutput > (TInput[] array, Converter < TInput, TOutput > converter);
// Summary:

public static TOutput[] ConvertAll < TInput, TOutput > (TInput[] array, Converter < TInput, TOutput > converter);
使用例子
public
string
[] GetRelationsForSources(
object
id)
{
vw_rel_InspirationsInSources[] entities =
Gateways.Default.Select < vw_rel_InspirationsInSources > (_Entity.vw_rel_Base.ItemId == id);
return Array.ConvertAll < vw_rel_InspirationsInSources, string > (entities,
delegate (vw_rel_InspirationsInSources input) { return input.Title; });
}
{
vw_rel_InspirationsInSources[] entities =
Gateways.Default.Select < vw_rel_InspirationsInSources > (_Entity.vw_rel_Base.ItemId == id);
return Array.ConvertAll < vw_rel_InspirationsInSources, string > (entities,
delegate (vw_rel_InspirationsInSources input) { return input.Title; });
}
