    <p>I've never encountered a problem like this in a console application - I hear some rather frightening beeping, the program (and my computer) freezes momentarily, and then the console just stops working - it doesn't even print an error message.</p> <p>I have <a href="http://projecteuler.net/project/cipher1.txt" rel="nofollow">this text file</a>. I read it as follows and then split the numbers into a list:</p> <pre><code>string path = @"C:\Users\owner\Documents\Quick Access\cipher1.txt"; string data = ""; using (StreamReader sr = new StreamReader(path)) { data = sr.ReadToEnd(); } List&lt;int&gt; encryptedNums = new List&lt;int&gt;(); foreach (string s in data.Split(',')) { encryptedNums.Add(Convert.ToInt32(s)); } </code></pre> <p>Each number represents an ASCII character. I want to concatenate these numbers into a string:</p> <pre><code>string encryptedString = ""; //WTF???? foreach (int n in encryptedNums) { encryptedString += (char)n; } </code></pre> <p>The <code>foreach</code> loop results in some very weird conversions. By printing out the characters one by one and comparing them with an <a href="http://www.asciitable.com/" rel="nofollow">ASCII table</a>, I see that the results are definitely <em>not</em> matching - for example, the number 2 results in a smiley-type figure. One of the conversions results in the beeping noise.</p> <p>Here's what really stymies me. I have a separate method where I do essentially the same thing - I have a list of integers and I try to convert them to a string:</p> <pre><code>string s = ""; foreach (int n in decrypted) { s += (char)n; } </code></pre> <p>But this actually results in a proper string! I don't see where my error is, and why the first conversion fails, while the second conversion (and unless I'm missing something, the code is the same) is fine. </p> <p>I'd appreciate any help.</p> <p>The code that ultimately causes is the crash is printing <code>encryptedString</code>.</p> <p><a href="http://pastebin.com/N4g64KWk" rel="nofollow">Here is the full code.</a></p>

    1. COI bet you want `n.ToString()` instead of `(char)n`

    2. CO@AustinSalonen No, that would get me a string representation of the number.. I need the corresponding ASCII character.

    3. COExplanations of the downvotes would be appreciated. The content of the question may be specific and localized but the question itself (I believe) is formulated generically.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
