Debug.WriteLine Method (String, Object[])

Writes a formatted message followed by a line terminator to the trace listeners in the Listeners collection.

Namespace:  System.Diagnostics
Assemblies:   System.Diagnostics.Debug (in System.Diagnostics.Debug.dll)
  System (in System.dll)

[ConditionalAttribute("DEBUG")]
public static void WriteLine(
	string format,
	params Object[] args
)

Parameters

format
Type: System.String

A composite format string (see Remarks) that contains text intermixed with zero or more format items, which correspond to objects in the args array.

args
Type: System.Object[]

An object array that contains zero or more objects to format.

This method uses the composite formatting feature of the .NET Framework to convert the value of an object to its text representation and embed that representation in a string.

The params [.NET Framework] keyword in the syntax for this method implies that the object array can be a single value. The exception to this is the String object. Explicit overloads take precedence, so an arg value of a single string will default to the Debug.WriteLine(String, String) overload.

By default, the output is written to an instance of DefaultTraceListener.

This method calls the TraceListener.WriteLine method of the trace listener.
