TextWriter.WriteLine Method (Object)

Writes the text representation of an object by calling the ToString method on that object, followed by a line terminator to the text string or stream.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

abstract WriteLine : 
        value:Object -> unit  
override WriteLine : 
        value:Object -> unit

Parameters

value
Type: System.Object

The object to write. If value is a null reference (Nothing in Visual Basic), only the line terminator is written.

ExceptionCondition
ObjectDisposedException

The TextWriter is closed.

IOException

An I/O error occurs.

This overload is equivalent to the Write(String, Object) overload. The FormatProvider property, if not a null reference (Nothing in Visual Basic), specifies the culture-specific formatting.

The line terminator is defined by the CoreNewLine field.
