Writing Text Files

What is translated > File Input and Output > Writing Text Files

Write and WriteLn write values to a TextFile or to the predefined Output file.

WRITE

Write outputs a value without adding a line ending.

Write(myFile, "Value: ");

Write(myFile, value);

Without a file parameter, Output is used:

Write("Value: ");

Write(value);

WRITELN

WriteLn writes a value and then adds a line ending.

WriteLn(myFile, "Finished");

WriteLn("Finished");

A parameterless WriteLn writes an empty line:

WriteLn();

FIELD WIDTH

Delphi output values can specify a minimum field width:

Write(myFile, value:10);

Depending on the translation pattern, this can be translated to:

Write(myFile, value, 10);

The value is right aligned and padded with spaces when it is shorter than the requested width.

Console output uses the corresponding overload without a TextFile parameter:

Write(value, 10);

DECIMAL PLACES

Real values can specify both a field width and a number of decimal places:

Write(myFile, value:10:2);

The corresponding C# runtime call is:

Write(myFile, value, 10, 2);

Console output uses:

Write(value, 10, 2);

Delphi real division must remain real division in C#.

For example:

Write(myFile, (double)i / 2, 5, 1);

MULTIPLE OUTPUT VALUES

The translator may split a Delphi Write or WriteLn statement into multiple C# calls.

For example:

WriteLn('':10, 'Path: ', Name);

can be translated to:

Write("", 10);

Write("Path: ");

WriteLn(Name);

All overloads without a TextFile parameter write to Output.
