    <p>This is the original java code it includes the <strong>PushbackInputStream</strong> class</p> <pre><code>public String readLine(InputStream in) throws IOException { char buf[] = new char[128]; int offset = 0; int ch; for (;;) { ch = in.read(); if (ch == -1 || ch == '\n') { break; } else if (ch == '\r') { int tmpch = in.read(); if (tmpch != '\n') { if (! (in instanceof PushbackInputStream))PushbackInputStream)) { in = new PushbackInputStream(in); } ((PushbackInputStream) in).unread(tmpch); } break; } else { if (offset == buf.length) { char tmpbuf[] = buf; buf = new char[tmpbuf.length * 2]; System.arraycopy(tmpbuf, 0, buf, 0, offset); } buf[offset++] = (char) ch; } } return String.copyValueOf(buf, 0, offset); } </code></pre> <p>Here is what i converted to C# , I implemented the <strong>PushbackInputstream</strong> with the <strong>peek</strong> method of the <strong>StreamReader</strong> class, however there is a keyword that i could not decipher like instanceof. Does the keyword "instanceof" matter in this situation? </p> <pre><code> public String readLine(NetworkStream nsStream) { using (StreamReader reader = new StreamReader(nsStream)) { char[] buffer = new char[128]; int offset = 0; int ch; for (; ; ) { ch = reader.Read(); if (ch == -1 || ch == '\n') { break; } else if (ch == '\r') { if ((reader.Peek()) == '\n') { break; } else { reader.Read(); } } else { if (offset == buffer.Length) { char[] tempBuffer = buffer; buffer = new char[tempBuffer.Length * 2]; Array.Copy(tempBuffer, 0, buffer, 0, offset); } buffer[offset++] = (char)ch; } } return new string(buffer); } } </code></pre> <p>Any comment would be appreciated!</p>

    1. CODitch that Java stuff and its oldschool newline detection. What you need is a [StreamReader](http://msdn.microsoft.com/en-us/library/system.io.streamreader.readline.aspx) and its `ReadLine` method.

    2. COI can't get your meaning, the readline method returns data as string and i want a char!

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.
