Question

I am working on this project still and I am running into a problem. Well here is what I need to do.

When the user clicks the “Save” button, write the selected record to
the file specified in txtFilePath (absolute path not relative) without
truncating the values currently inside and handle any exceptions that arise.

Ok here is my code:

 private void Save_Click(object sender, EventArgs e)
    {

        string filePath = txtFilePath.Text;

        if (!File.Exists(filePath))
        {
            FileStream fs = File.Create(filePath);
            fs.Close();
        }

        using (FileStream fs = new FileStream(filePath, FileMode.Create, FileAccess.Write))
        {
            using (StreamWriter sw = new StreamWriter(fs))
            {
                foreach (string line in employeeList.Items)
                {
                    sw.WriteLine(line);
                }
            }
        }
            }

Now when I go onto my program and want to save something from the employeelist.text that its not being saved to the place I am saving it at. I don;t know if I am missing something in my code or what but it will not save. Here is an example:

I add a person name to this list in employeelist and in the textbox I
have a file called C:\employess\employeelist.txt I want to save it to.
I click the save button then I go to that employeelist and it is not
being saved.

I don’t know what I am doing wrong I have been looking online for a solution but I haven’t found anything yet. Thanks

Some things to double-check:

• Make sure you don’t have the employeelist.txt file open when you’re testing
• Make sure you don’t have invalid characters in your file name
• Make sure your application has permission to save the file to the location you specified
• Use the debugger to step-through your code and look for swallowed exceptions — there must be a reason the file is not created.
• Check that your Save_Click event is wired up to your button — is the code in your example even running?

Once you check those things, you may want to follow this example for the create vs. append requirement of your project:

string path = txtFilePath.Text;

// This text is added only once to the file.
if (!File.Exists(path)) 
{
    using (StreamWriter sw = File.CreateText(path)) 
    {
        foreach (var line in employeeList.Items)
            sw.WriteLine(line.ToString());
    }   
} 
else 
{
    using (StreamWriter sw = File.AppendText(path)) 
    {
        foreach (var line in employeeList.Items)
            sw.WriteLine(line.ToString());
    }
}

This will create the file if it doesn’t exist, or append to it if it does.
