Changing a Variable A-Z if file exists(C#)
<p>Hey everyone I am currently getting the next variable based on if a file exists, but know there must be an easier way. This thread <a href="http://stackoverflow.com/questions/1011732/iterating-through-the-alphabet-c-sharp-a-caz">Iterating through the Alphabet - C# a-caz</a> gave me some good insight, but I am having a bit of a problem Implementing it with what I have. Any suggestions would be really appreciated. Thanks</p>

<pre><code>//Generate Motor Spacer Part Number
textBox3.Text = "MLB028A-MTRSPR-" + "z" + "-" + "y";
if (comboBox3.Text == "28mm (NEMA 11)") textBox3.Text = textBox3.Text.Replace("z", "B");
if (comboBox3.Text == "28mm (NEMA 11)") textBox3.Text = textBox3.Text.Replace("y", "A");

//Generate Motor Spacer Part Descriptions
textBox5.Text = "SPACER, " + comboBox3.Text + ", CFG-" + "y" + " MLB028";
if (comboBox3.Text == "28mm (NEMA 11)") textBox5.Text = textBox5.Text.Replace("y", "A");

string B = @"C:\Engineering\Engineering\SW Automation\Linear Actuator Technology\MLC Series\Models\MLB028Z-MTRSPR-B-A.SLDPRT";
if (File.Exists(B))
{
   testBox3.Text = textBox3.Text.Replace("y", "B");
   textBox5.Text = textBox5.Text.Replace("y", "B");
}

string C = @"C:\Engineering\Engineering\SW Automation\Linear Actuator Technology\MLC Series\Models\MLB028Z-MTRSPR-B-B.SLDPRT";
if (File.Exists(C))
{
   testBox3.Text = textBox3.Text.Replace("y", "C");
   textBox5.Text = textBox5.Text.Replace("y", "C");
}
</code></pre>
