Reads the specified flag, returning true if it is found.
public bool ReadFlag(string name)
| parameter | description |
|---|---|
| name | The name of the specified flag. |
True if the specified flag was found on the command line.
| exception | condition |
|---|---|
| ArgumentNullException | name is null. |
| ArgumentException | One of the names is empty. |
If the flag is found, the method returns true and the flag is removed. If ReadFlag is called again with the same name, it will return false, unless the same flag appears twice on the command line.
To support multiple names for the same flag, use a | to separate them, e.g. use help|h|? to support three different names for a help flag.
Single-character names use a single hyphen, e.g. -h. Longer names use a double hyphen, e.g. --help.
