The OpenWrite method in the BaseFileSystem class is used to open a file for writing. It returns a System.IO.Stream that can be used to write data to the specified file. The method requires a file path and a FileMode parameter to determine how the file should be opened.
To use the OpenWrite method, you need to provide the path to the file you want to write to and specify the FileMode. The FileMode parameter determines whether the file is created, overwritten, or appended to. Common FileMode values include:
FileMode.Create: Specifies that the operating system should create a new file. If the file already exists, it will be overwritten.FileMode.Append: Opens the file if it exists and seeks to the end of the file, or creates a new file. This requires FileAccess.Write.FileMode.OpenOrCreate: Specifies that the operating system should open a file if it exists; otherwise, a new file should be created.Ensure that you handle exceptions such as IOException or UnauthorizedAccessException that may occur during file operations.
// Example of using OpenWrite to write to a file
// Create an instance of BaseFileSystem
BaseFileSystem fileSystem = new BaseFileSystem();
// Define the path and mode
string filePath = "example.txt";
FileMode mode = FileMode.Create;
// Open the file for writing
using (Stream stream = fileSystem.OpenWrite(filePath, mode))
{
// Convert the string to bytes
byte[] data = System.Text.Encoding.UTF8.GetBytes("Hello, Sandbox!");
// Write data to the file
stream.Write(data, 0, data.Length);
