IBinaryReader.ReadListBegin

Syntax

ReadListBegin;

Description

The ReadListBegin method reads an indicator of a page start from a binary file.

Example

Executing the example requires the 1.dat binary file to be present in the root of the disc C.

Sub UserProc;
Var
    File1: IFileInfo;
    BinR: IBinaryReader;
    IntList: IArrayList;
Begin
    File1:=New FileInfo.Attach("c:\1.dat");
    IntList:=New ArrayList.Create;
    If File1.Exists Then
        BinR:=File1.OpenBinaryReader;
        BinR.ReadListBegin;
        While Not BinR.EndOfList Do
            IntList.Add(BinR.ReadInteger);
        End While;
        BinR.ReadListEnd;
    End If;
    Dispose File1;
End Sub UserProc;

After executing the example integer values from the 1.dat file are read into the IntList array. An indicator of the page beginning is read before reading an array.
