C# extensions for daily usage
Hi everyone! Today I want to share my extensions which I am using in my daily routine.
I want to say, that I used them in every standalone project I worked for (and sometimes job projects) Go and grab them
I won’t update this article in the future. So, check link above for getting newest ones.
Collection extensions
public static List<T> NullToEmpty<T>(this List<T> source)
{
return source ?? new List<T>();
}
public static T[] ExpandArray<T>(this T[] array, T item)
{
if (array == null || array.Length == 0)
{
array = new[] { item };
return array;
}
var expandedArray = new T[array.Length + 1];
Array.Copy(array, expandedArray, array.Length);
expandedArray[array.Length] = item;
return expandedArray;
}
String’s extensions
public static bool IsNullOrEmpty(this string value)
{
return string.IsNullOrEmpty(value);
}
public static bool NotNullOrEmpty(this string value)
{
return !string.IsNullOrEmpty(value);
}
Json helpers (JSON.NET is required)
public static string ToJson<T>(this T obj)
{
return JsonConvert.SerializeObject(obj, Formatting.Indented);
}
Entity Framework
public static IQueryable<TEntity> Includes<TEntity>(this IQueryable<TEntity> source,
params Expression<Func<TEntity, object>>[] includes)
where TEntity : class
{
foreach (var include in includes)
{
source = source.Include(include);
}
return source;
}
Conclusion
That’s all. I’ll be happy, If this link helps you.
