Create(Stream: IIOStream);
Stream. The stream, from which text data is read.
The Create constructor creates an object that enables the user to read text data.
Specify the stream connected with the place where text data is stored as a value of the Stream parameter. Initialize the object of one of the following classes and specify it as a value of the Stream parameter:
FileStream. The stream connected with the file on the hard drive.
MemoryStream. The stream in the computer memory.
Sub UserProc;
Var
f: IFileStream;
TxtRead: ITextReader;
s: String;
Begin
If File.Exists("c:\File.txt") Then
f := New FileStream.Create("c:\File.txt", FileOpenMode.Read, FileShare.DenyNone);
TxtRead := New TextReader.Create(f);
s := TxtRead.ReadLine;
Debug.WriteLine(s);
Dispose f;
End If;
End Sub UserProc;
On executing the example it is checked if the File.txt file exists. If the file exists, a character string will be read from it. The read value will be displayed in the development environment console.
