Text Files

What is translated > File Input and Output > Text Files

A Delphi TextFile variable is translated to the C# class TextFile.

TextFile is derived from TTextRec. TTextRec contains the shared implementation for text input and output.

A text file variable is normally initialized as follows:

TextFile myFile = TextFile.CreateRecord();

AssignFile associates the variable with a file name:

AssignFile(myFile, "Test.txt");

Rewrite creates or replaces the file and opens it for writing:

Rewrite(myFile);

Write and WriteLn write values to the file:

WriteLn(myFile, "Hello");

WriteLn(myFile, "World");

Append reopens an existing text file and writes new data at the end:

CloseFile(myFile);

Append(myFile);

WriteLn(myFile, "Final line");

Reset opens the file for reading:

CloseFile(myFile);

Reset(myFile);

CloseFile closes the current reader or writer. It does not remove the file name assigned by AssignFile. The same TextFile variable can therefore be reopened.
