C# help for student - format exception

O.k. I'm trying to write a program for school. the code below (I'm not posting the whole program unless you need to see it) is giving me a format exception when it hits the deptarray line?? Any ideas why??? It's reading data in from a file. It looks just like the code that was in the teacher's example?? Any help would be appreciated as I"m pulling my hair out.

static void ParseLineIn(string lineIn, uint i)

{

string[] words = new string[5];

lineIn = lineIn.Trim();

while (Regex.IsMatch(lineIn, "[ ] {2}"))

lineIn = lineIn.Replace(" ", " ");

words = lineIn.Split(' ');

lastNameArray[i] = words[0];

firstNameArray[i] = words[1];

deptArray[i] = UInt32.Parse(words[2]);

rateArray[i] = Double.Parse(words[3]);

hoursArray[i] = Double.Parse(words[4]);

}

static void InputEmployeeData()

{

uint i;

string lineIn;

i = 0;

while ((lineIn = fileIn.ReadLine()) != null)

{

i++;

ParseLineIn(lineIn, i);

}

numOfEmployees = i;

}

How did you declare deptArray? And right before the exception occurs, what is the value of words[2] ?

Assuming deptArray is declared as uint[] deptArray, format exception will occur if the current value of words[2] is not a numeric value

The dept is a number (1, 2, 3, or 4). Any other ideas??

The most likely explanation for the format exception is that the department is a string (e.g. "Sales") rather than a number.
