Looks good to me. Possible example:
class Program
{
static void Main(string[] args)
{
string stringToWrite = “Hi, My name is Bob”;
StreamWriter writer = null;
writer = new StreamWriter(@”C:\temp\target.txt”);
writer.Write(stringToWrite);
writer.Close();
}
}

class Program

static void Main(string[] args)
{
string stringToWrite = “Hi, My name is Bob”;
StreamWriter writer = null;
writer = new StreamWriter(@”C:\temp\target.txt”);
writer.Write(stringToWrite);
writer.Close();
}
}
WORK!

agree. Just would like to note that StreamWriter doesn’t contain Open()
