C # Get operating system log information

Using C # Programming, view the system log, introduce two log classes: EventLog and EventLogEntry classes, and interact with the system log.

. NET Framework class library provides the EventLog class and the EventLogEntry class to interact with the system log. They belong to the System.Diagnostics namespace.

First declare a variable: Private Eventlogentrycollection eventcollection represents a collection of system logs.

The main properties of the EventLog class are:

Entris returns a Eventlogentrycollection value that represents the contents of the event log.

Log Gets or returns the name of the journal, where the application log is application, the system log is systems, and the security log is secure, and the default value is an empty string.

Logdisplayname gets the friendly name of the event log

MachineName Gets or sets the name of the computer on which the event is read or written

Source Gets or sets the names of the sources to register and use when writing to the event log

The Evententrycollection class defines the size and enumerator of the EventLogEntry instance collection.

Some of the main properties of the EventLogEntry class are as follows:

Category gets the text corresponding to the categorynumber of the item

Categorynumber Gets the category number of the item

Data gets the binary that corresponds to the item

EntryType Gets the event type for the item, whose value belongs to the EventLogEntryType enumeration, whose main members are as follows:

Successaudit successful audit event. It indicates that auditing access attempts to succeed, such as security events that occur at successful logon

Warning Warning event. It indicates a problem that is not immediately important, but this problem may indicate a condition that will cause problems in the future.

EventID the application-specific event identifier for this event entry

Index gets the entry of the item in the event log

MachineName gets the name of the computer on which the item was generated

Message gets localized messages with this event

Replacementstrings get the replacement string for the item

Source gets the name of the application that generated the event

TimeGenerated gets the local time that generated the event

TimeWritten gets the local time when the log is written to the event
