On4Net.Extensions.Common

Shared helpers: extension methods on string, byte[], and other types; regex validation constants; and a Culture struct. Namespace: On4Net.Extensions.Common.

Dependencies: Newtonsoft.Json; StringExtension.cs includes a static using for System.Formats.Asn1 (can be removed if unused).

ObjectExtension — ObjectExtension.cs

Method What it does
Compress(this byte[] data) Compresses a byte array using GZipStream; returns compressed bytes.
Decompress(this byte[] data) Decompresses GZip-compressed bytes; returns raw bytes.
DecompressMemoryStream(this byte[] data) Same as decompress but returns a MemoryStream (e.g. for HTTP responses).
GetNumberByGuid(this Guid guid) XOR-combines GUID bytes into a numeric string (short/display code).
GetNumberByGuid(this string arg) Parses string as GUID (via ToGuid) then returns GetNumberByGuid(Guid).
ConvertToDatatable<T>(this IList<T> data, string tableName) Builds a DataTable from public properties of T and fills rows from the list.
BindDataClass<T>(this T contractData, T enjectData, bool isCheckValue = false) Copies same-named property values from enjectData to contractData via reflection; optional skip of default/null values.
CreateInstance(this string ClassName) Type.GetType + Activator.CreateInstance for a type name string.
CreateInstance<T>(this T ClassName) where T : class Creates a new instance of T; the receiver is only used as extension target.
ToDateTime(this long unixTime) Converts Unix epoch seconds to local DateTime.
GetTime() Returns current UTC time as Unix seconds (not an extension).
ToEnum<T>(this string enumString) where T : Enum Parses string to enum; throws ArgumentException if not defined.
ToJsonString<T>(this T @object, JsonSerializerSettings settings = null, Formatting formatting = None) Newtonsoft serialize; default ignores nulls.
FromJsonString<T>(this string json) Newtonsoft deserialize to T; throws if null/whitespace.

DefaultValue(Type) in the same file is private (used by BindDataClass).

StringExtension — StringExtension.cs

Method What it does
IsNullOrEmpty(this string obj, bool isNullOrWhiteSpace = true) IsNullOrWhiteSpace or IsNullOrEmpty based on flag.
IsNotNullOrEmpty(this string obj, bool isNullOrWhiteSpace = true) Negation of the above.
Add_Zero_Before(this string InputStr, int OutLen) Left-pads with zeros to length OutLen (accounting-style).
Add_Zero_After(this string InputStr, int OutLen) Right-pads with zeros to length OutLen.
Add_SpaceAfter(this string InStr, int OutLen) Right-pads with spaces to length OutLen.
ToDecimalNull / ToDecimal Safe parse to decimal? / decimal (default if fail).
ToInt16Null / ToInt16 Safe parse to short? / short.
ToByteNull / ToByte Safe parse to byte? / byte.
ToInt32Null / ToInt32 Safe parse to int? / int.
ToInt64Null / ToInt64 Safe parse to long? / long.
ToDoubleNull / ToDouble Safe parse to double? / double.
ToFloatNull / ToFloat Safe parse to float? / float.
ToGuidNull / ToGuid Parse GUID; ToGuid returns Guid.Empty on failure.
IsRtl(this string culture) Uses CultureInfo.GetCultureInfo; returns TextInfo.IsRightToLeft.
GetDirection(this string culture) Returns "rtl" or "ltr".
GetLanguageCulture(this string culture) First segment of xx-YY (e.g. fa from fa-IR).
GetCountryCulture(this string culture) Second segment; throws if culture format is invalid.

RegExExtesion — RegExExtesion.cs (typo in type name)

Public regex pattern constants: RegEx_Digit, RegEx_Decimal, RegEx_Email, RegEx_WebAddress, RegEx_Time12, RegEx_Time24, RegEx_TimeDuration, RegEx_IPAddress, RegEx_Password.

Method What it does
IsMatch_Digit … IsMatch_Password (this string InputString) Each wraps the matching RegEx_* constant with Regex.IsMatch.
IsExpressionValid(this string stringForValidate, string pattern) Validates with a custom pattern; returns false if input is null or empty.

IsMatch (two strings) is private in this class.

Culture — Culture.cs

Member What it does
Culture.English Static preset: CurrentCulture and DefaultCulture = en-US.
