Specifies what messages to output for the Debug, Trace and TraceSwitch classes.
public enum class TraceLevelpublic enum TraceLeveltype TraceLevel = Public Enum TraceLevel- Inheritance
Fields
| Name | Value | Description |
|---|---|---|
| Off | 0 | Output no tracing and debugging messages. |
| Error | 1 | Output error-handling messages. |
| Warning | 2 | Output warnings and error-handling messages. |
| Info | 3 | Output informational messages, warnings, and error-handling messages. |
| Verbose | 4 | Output all debugging and tracing 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:DEBUGflag to the compiler command line when you compile your code, or you can add#define DEBUGto the top of your file. In Visual Basic, add the/d:DEBUG=Trueflag to the compiler command line.To enable tracing in C#, add the
/d:TRACEflag to the compiler command line when you compile your code, or add#define TRACEto the top of your file. In Visual Basic, add the/d:TRACE=Trueflag 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.
| Trace Level | Configuration File Value |
|---|---|
| Off | 0 |
| Error | 1 |
| Warning | 2 |
| Info | 3 |
| Verbose | 4 |
