Class MessageFilterExpression

Defines an expression used for log message filtering. Important: it is not a good practice to create many different scopes as it leads to creation of many assemblies dynamically

Constructors

MessageFilterExpression(String)

Creates a new expression in a default logging filter scope. This .ctor will fail if at least one expression from this scope has already been compiled

Declaration
public MessageFilterExpression(string expr)
Parameters
Type Name Description
System.String expr

MessageFilterExpression(String, String, IEnumerable<String>, IEnumerable<String>)

Use this .ctor to specify a different scope name. Every unique scope name gets compiled into a new assembly, consequently it is not a good practice to create many different scopes. This .ctor will fail if at least one expression from this scope has already been compiled

Declaration
public MessageFilterExpression(string scope, string expr, IEnumerable<string> referencedAssemblies = null, IEnumerable<string> usings = null)
Parameters
Type Name Description
System.String scope
System.String expr
System.Collections.Generic.IEnumerable<System.String> referencedAssemblies
System.Collections.Generic.IEnumerable<System.String> usings

Fields

Declaration
public const string SCOPE = "_AZOS._Log._Filtering"
