I am currently working on an assignment for school where I am trying to write a 2D string array into a text file. I have the array and know its working fine however every time I try to read the file into Streamwriter I get "System.ArgumentException: 'Illegal characters in path.'". I am relatively new to C# and I have no idea how to fix this.
This is my code. I just need to know how to write my 2D array into the text file without getting this error. Thanks, all and any help is much appreciated!
// This line under is where the error happens
using (var sw = new StreamWriter(Harvey_Norman.Properties.Resources.InventoryList))
{
for (int i = 0; i < 4; i++)
{
for (int j = 0; j < 3; j++)
{
sw.Write(InventoryArray[i, j] + " ");
}
sw.Write("\n");
}
sw.Flush();
sw.Close();
}
My guess is that Harvey_Norman.Properties.Resources.InventoryList is a resource in your project that is typed as a string-- and the value of that string is not a valid path for your operating system.
StreamWriter will either take a string, in which case it expects to open a file with the path of that string; or it will take a stream, and you can write to that stream. It looks like you are trying to do the former; but you need to check the value of that resource to see if it is a vaild path.
