Parameters

path

A string containing the name of the file to be opened for writing. [Edit]

Returns

A writable System.IO.FileStream that writes to the file specified by path. [Edit]

Permissions

Type	Reason
System.Security.Permissions.FileIOPermission [Edit]	Requires permission to write the specified file. See System.Security.Permissions.FileIOPermissionAccess.Write.

Exceptions

Type	Reason
System.Security.SecurityException	The caller does not have the required permission. [Edit]
ArgumentException	path is a zero-length string, contains only white space, or contains one or more implementation-specific invalid characters. [Edit]
System.IO.FileNotFoundException	path was not found. [Edit]
ArgumentNullException	path is null. [Edit]
System.IO.DirectoryNotFoundException	The directory information specified in path was not found. [Edit]
UnauthorizedAccessException	The caller does not have the required permission. [Edit]

Remarks

This method is equivalent to System.IO.FileStream (path, FileMode.OpenOrCreate, FileAccess.Write, FileShare.None ).

The path argument is permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory.

Note: To obtain the current working directory, see Directory.GetCurrentDirectory.
