OpenOrCreate

If the file doesn't exist, create it.

If it does exist, do not truncate it.

Create

If the file doesn't exist, create it.

If it does exists, truncate it.

Quote:

OpenOrCreate Specifies that the operating system should open a file if it exists; otherwise, a new file should be created. If the file is opened with FileAccess.Read, FileIOPermissionAccess.Read permission is required. If the file access isFileAccess.Write, FileIOPermissionAccess.Write permission is required. If the file is opened withFileAccess.ReadWrite, both FileIOPermissionAccess.Read and FileIOPermissionAccess.Write permissions are required.

using (var s = File.Open(path, FileMode.OpenOrCreate))
using (var w = new StreamWriter(s))
{
    w.Write("0123456789");
    w.Flush();
}

// File now contains: 0123456789

using (var s = File.Open(path, FileMode.OpenOrCreate))
using (var w = new StreamWriter(s))
{
    w.Write("ABC");
    w.Flush();
}

// File now contains: ABC3456789

The documentation is quite clear

using (Stream stream1 = new FileStream(path1, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
{
    dcs1.WriteObject(stream1, this.TheData1);
    stream1.Position = 0L; // as if this would help
    stream1.Close(); // throwing salt over shoulder
}

using (Stream stream1 = new FileStream(path1, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None))
{
    stream1.Position = 0L;
    dcs1.WriteObject(stream1, this.TheData1);
