LogStore Constructor (String, FileMode, FileAccess)
Initializes a new instance of the LogStore class with the specified path, mode, and access.
Assembly: System.IO.Log (in System.IO.Log.dll)
- Type: System.String
A relative or absolute path for the base file of the log store to open.
- Type: System.IO.FileMode
One of the FileMode values that determines how to open or create the store.
path is null.
path is an empty string ("").
path contains only white space.
path contains one or more invalid characters.
mode contains an invalid value.
access contains an invalid value.
The file cannot be found.
An I/O error occurs when opening the log store.
Access for the specified log store is denied by the operating system.
LogStore cannot be used because the required Common Log File System (CLFS) component is not installed. Install the CLFS component if it is available for your platform or use the FileRecordSequence class instead.
There is not enough memory to continue the execution of a program.
Use this constructor to open a new log store with the specified path, mode, and access. The store is opened sharing read access.
The path parameter should use the following syntax:
log:<physical log name>[::<log client name>]
where <physical log name> is a valid path to a log file, and <log client name> is a unique client identifier. A log store should be either a physical log store or a virtual log store, but not both. Once a log store has been created physically or virtually, it remains so for its lifetime. A physical log store is created by specifying only the physical log name. A virtual log store is created by specifying both the physical log name and the log client name.
Clients that share the same physical log name share the same extents collection and policy.
