TraceLevel Enum

Definition

Specifies what messages to output for the Debug, Trace and TraceSwitch classes.

public enum class TraceLevel
public enum TraceLevel
type TraceLevel = 
Public Enum TraceLevel
Inheritance
TraceLevel

Fields

Error 1

Output error-handling messages.

Info 3

Output informational messages, warnings, and error-handling messages.

Off 0

Output no tracing and debugging messages.

Verbose 4

Output all debugging and tracing messages.

Warning 2

Output warnings and error-handling messages.

Remarks

This enumeration is used by the TraceSwitch class.

You must enable tracing or debugging to use a switch. The following syntax is compiler specific. If you use compilers other than C# or Visual Basic, refer to the documentation for your compiler.

  • To enable debugging in C#, add the /d:DEBUG flag to the compiler command line when you compile your code, or you can add #define DEBUG to the top of your file. In Visual Basic, add the /d:DEBUG=True flag to the compiler command line.

  • To enable tracing in C#, add the /d:TRACE flag to the compiler command line when you compile your code, or add #define TRACE to the top of your file. In Visual Basic, add the /d:TRACE=True flag to the compiler command line.

For more information on instrumenting your application, see Debug and Trace.

In .NET Framework app configuration files, you can use text to specify the value for a switch. For example, true for a BooleanSwitch, or the text representing an enumeration value such as Error for a TraceSwitch. The line <add name="mySwitch" value="Error" /> is equivalent to <add name="mySwitch" value="1" />. You can also set trace levels using the integer value of the enumeration. The following table shows the relationship between the TraceLevel enumeration members and their corresponding configuration file entries.
