Interesting message from Mono C# compiler
List<Position> result;
// insert the questions into a structure to make them easy to search
while ((line = data.ReadLine ()) != null) {
//Console.WriteLine (”{0}”, line);
string[] words = line.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
wordPosition = 0;
foreach (string word in words) {
if ((result = noSig.Find(word)).Count != 0)
significant = true;
else
significant = false;
//Console.WriteLine (”{0}: {1} {2} ({3}))”, lineCount, wordPosition, word, significant);
Position p
= new Position (lineCount, wordPosition++, significant);
wordTree.Add (word, p);
}
lineCount++;
}
First off, hard to believe it’s been so long since I posted here.
I ran across an interesting little problem the latest C# compiler for mono has in analyzing this bit of code:
List<Position> result;
// insert the questions into a structure to make them easy to search
while ((line = data.ReadLine ()) != null) {
string[] words = line.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
wordPosition = 0;
foreach (string word in words) {
if ((result = noSig.Find(word)).Count != 0)
significant = true;
else
significant = false;
Position p = new Position (lineCount, wordPosition++, significant);
wordTree.Add (word, p);
}
lineCount++;
}
This code gives me the warning:
The variable ‘result’ is assigned but never used (CS0219)
The code shown in red is obviously using the variable. A bit indirectly, perhaps.
Since I had been editing code and renaming variables I thought that I had just missed one, so I deleted it. Which caused the next problem, that the variable result was not defined :)
Not a big deal, I just found it amusing.
