    Methods

    AcctNoCompare(String, String)

    Compare two account numbers, ignoring leading zeroes.

    Declaration
    public static bool AcctNoCompare(string sAcctNo1, string sAcctNo2)
    Parameters
    Type Name Description
    System.String sAcctNo1
    System.String sAcctNo2
    Returns
    Type Description

    AppendRemittanceInformationLine(SepaTransactionDetails, String)

    Appends a text line to the RemittanceInformation.

    Declaration
    public static void AppendRemittanceInformationLine(this SepaTransactionDetails aTxn, string sRmtInfLine)
    Parameters
    Type Name Description
    SepaTransactionDetails aTxn

    The transaction where the remittance information line shall be added to. Must not be null.

    System.String sRmtInfLine

    The text line to be appended. If this is null or empty, then this method does nothing. If the line is longer than MaxRmtInfLen, it is truncated at MaxRmtInfLen.

    Remarks

    If the RemittanceInformation is empty, then the given sRmtInfLine will be set as the only content of that property. Otherwise a Environment.NewLine is appended to separate the appended line from the existing content.

    CoalesceSpaces(String)

    Declaration
    public static string CoalesceSpaces(string sText)
    Parameters
    Type Name Description
    System.String sText
    Returns

    System.String

    CreateFakeCreditCardNo(String, Char)

    Creates a fake credit card number from a masked credit card number by replacing the mask character with zeroes and fixing the Luhn check digit accordingly.

    Declaration
    public static string CreateFakeCreditCardNo(string sMaskedCreditCardNo, char chMaskChar = '*')
    Parameters
    Type Name Description
    System.String sMaskedCreditCardNo

    A masked credit card number that consists solely of digits and the chMaskChar. The length of this string must match the length of the original credit card number.

    System.Char chMaskChar
    Returns
    Type Description
    System.String

    If the credit card number did not contain any chMaskChar, then it is returned as is. Otherwise a string is constructed, where all the mask characters are replaced by '0', and the last mask character is replaced with a digit that ensures that the resulting string passes the Luhn check.

    Exceptions
    Type Condition
    System.ArgumentNullException

    The parameter sMaskedCreditCardNo was null.

    System.ArgumentException

    The length of sMaskedCreditCardNo is not a valid credit card number length. -or- The sMaskedCreditCardNo did contain a character that is neither a digit nor the chMaskChar.

    IsValidGermanBankCode(String)

    Checks whether the given bank code consists of exactly eight digits.

    Declaration
    public static bool IsValidGermanBankCode(string sBankCode)
    Parameters
    Type Name Description
    System.String sBankCode
    Returns
    Type Description
    System.Boolean
    Remarks

    This method does not check whether the bank code actually exists, and it also does not check whether the bank code begins with a digit in the range 1 through 8.

    IsValidUTF8(Byte[], Int32, Int32)

    Determines if a buffer is a valid UTF-8 encoding.

    Declaration
    public static bool IsValidUTF8(byte[] vbData, int nOffset, int nLength)
    Parameters
    Type Name Description
    System.Byte[] vbData
    System.Int32 nOffset
    System.Int32 nLength
    Returns
    Type Description
    System.Boolean

    If the buffer is a valid UTF-8 encoding, then true is returned. This includes buffers that contain solely ASCII bytes. If the buffer is not a valid UTF-8 encoding, then false is returned.

    NullTrim(String, Int32)

    Trim whitespace and truncate string. Returns null when result is an empty string.

    Declaration
    public static string NullTrim(string s, int nMaxLength = 2147483647)
    Parameters
    Type Name Description
    System.String s

    The string from which to trim leading and trailing whitespace. If this is null, then this method also returns null.

    System.Int32 nMaxLength

    The maximum length of the trimmed string. If, after trimming, the given string is longer than this, then only a sub-string with the given maximum length will be returned.

    Returns
    Type Description
    System.String

    If, after trimming, the resulting string is an empty string, then null is returned instead of an empty string.

    ParseDate(String, String)

    Declaration
    public static DateTime ParseDate(string sDate, string sOrder = "DMY")
    Parameters
    Type Name Description
    System.String sDate

    Date given as a string that starts with three digits groups, separated by a non-digit character. Any characters following the last digit of the three digit groups are ignored. Possible inputs are "20.02.2013" or "2012-04-09".

    System.String sOrder

    The order of the date elements. Must be a string containing the three characters 'D', 'M', and 'Y' in the expected order of the date elements. The default value is "DMY". If the date is given in ISO "YYYY-MM-DD" format, then it is always parsed as such, regardless of the value of this parameter.

    Returns
    Type Description
    System.DateTime

    The parsed date or DateTime.MinValue if the given date string was null or empty. If the date cannot be parsed an exception is thrown.

    Remarks

    Two digit years smaller than 80 are assumed as 2000 through 2079. All other two digit years are assumed as 1980 through 1999.

    A day in the range from 28 through 31 that exceeds the maximum number of days in the given month is converted to the actual maximum day of the month. For example, a date 2017-04-31 is parsed and converted to 2017-04-30. This is done in order to cope with financial virtual date representations.

    A date of 0000-00-00 is parsed as DateTime.MinValue.

    Exceptions
    Type Condition
    System.ArgumentNullException

    The parameter sOrder was null.

    System.ArgumentException

    The parameter sOrder did not consist of the three letters 'Y', 'M', and 'D' in any order.
