Creates an empty FinTS segment of the given segment type.

Declaration
public FinSegment(string sSegmentType, int nSegmentVersion)
Parameters
Type Name Description

The segment type of the new segment, e.g. "HKUEB". This must not be empty or longer than 6 characters.
System.Int32 nSegmentVersion

FinSegment(String, Int32, Nullable<Int32>)

Creates an empty FinTS segment of the given segment type.

Declaration
public FinSegment(string sSegmentType, int nSegmentVersion, int? nRefSegNo)
Parameters
Type Name Description
System.String sSegmentType

The segment type of the new segment, e.g. "HKUEB". This must not be empty or longer than 6 characters.
System.Int32 nSegmentVersion

Properties

Elements

Provides the complete collection of FinDataElement instances of this segment, including the segment header elements.

Declaration
public IList Elements { get; }
Property Value
Type Description
System.Collections.IList

Item[Int32, Int32]

Direct access to the data elements stored in this container, indexed by its DEG,GD position.

Declaration
public FinDataElement this[int nDEG, int nGD] { get; set; }
Parameters
Type Name Description
System.Int32 nDEG
System.Int32 nGD
Property Value
Type Description
FinDataElement
Remarks

In either case the given nDEG and nGD indices are 1-based and must not be zero or negative.

Attempting to retrieve a data element that does not exist will return a null reference.

Inserting a data element using this indexer will implicitly update the DEG and GD properties of the given data element in order to match the explicitly given nDEG and nGD indices.

MaxDEG

Provides the highest DEG position that this segment uses.

Declaration
public int MaxDEG { get; }
Property Value
Type Description
System.Int32
Remarks

For an empty segment this is still 1, as the segment header is always there.

RefSegNo

Convenient access to the reference segment number of this segment.

Declaration
public int RefSegNo { get; set; }
Property Value
Type Description
System.Int32
Remarks

This property is just a short-cut to the optional integer element at position 1,4. When setting this property the provided integer must be in the allowed range from 1 through 999.

SegNo

Convenient access to the segment number of this segment.

Declaration
public int SegNo { get; set; }
Property Value
Type Description
System.Int32
Remarks

This property is just a short-cut to the integer element at position 1,2. When setting this property the provided integer must exceed 1.

SegTypeIssuer

The issuer of this segment type. This is a single letter.

Declaration
public char SegTypeIssuer { get; }
Property Value
Type Description
System.Char
Remarks

All FinTS defined standard segments start with the letter 'H'. Segments defined by other parties start with another letter, e.g. 'D' for Segments defined by the Sparkasse organisation. This property provides convenient access to this starting letter of the segment Type.

If the segment Type was not set, then this property returns 'H'.

Type

Convenient access to the segment type element of this segment.

Declaration
public string Type { get; set; }
Property Value
Type Description
System.String
Remarks

This property is just a short-cut to the string element at position 1,1. When setting this property the provided string must not be empty and must not be longer than 6 characters.

Version

Convenient access to the segment version of this segment.

Declaration
public int Version { get; set; }
Property Value
Type Description
System.Int32
Remarks

This property is just a short-cut to the integer element at position 1,3. When setting this property the provided integer must be in the allowed range from 0 through 999.

Methods

GetAccount(Int32, Boolean)

Reads an account data element group and returns a new FinAcct instance for it.

Declaration
public FinAcct GetAccount(int nDEG, bool fWithSubAcctCharacteristic)
Parameters
Type Name Description
System.Int32 nDEG

The DEG position of the account data element group to be read.
System.Boolean fWithSubAcctCharacteristic

If this is true, then a DEG including a subaccount characteristic according to HBCI 2.2 and later will be expected. If this is false, then an old fashioned DEG is expected. Note that this flag must be appropriately set, even if the given account information does not include a subaccount characteristic, because it influences the expected overall layout of the DEG.
Returns
Type Description
FinAcct

If the data element group is nonempty and contains a syntactically valid account specification, then the account information is stored in a new FinAcct instance and returned to the caller. If the DEG is completely empty, then null is returned.
