CSharpTest.Net.Library Assembly > CSharpTest.Net.IO Namespace : ReplaceFile Class

Glossary Item Box

Creates a temp file based on the given file being replaced and when a call to Commit() is made the target file is replaced with the current contents of the temporary file. Use the TransactFile if you MUST be certain to succeed then Commit(), otherwise this implementation provides a 'good-enough' transaction and is optimized for larger files.
