    <p>Here's what I came up with as a solution:</p> <p>PostSharp or another AOP solution wasn't really practical in this situation, so unfortunately I had to abandon that idea.</p> <p>It appears that while it is possible to parameter names and types using reflection, the only way to access the runtime values is with a debugger attached.</p> <p>See here for more info:</p> <p><a href="https://stackoverflow.com/questions/157911/in-a-net-exception-how-to-get-a-stacktrace-with-argument-values">StackOverflow</a></p> <p><a href="http://groups.google.co.uk/group/microsoft.public.dotnet.framework/browse_thread/thread/1bf8888efb2c7076/de051fc487c3900?hl=en&amp;" rel="nofollow noreferrer">microsoft.public.dotnet.framework</a></p> <p>So that still left me with the problem of ~50 methods that needed this logging adding by hand.</p> <p>Reflection to the rescue...</p> <pre><code>public String GetMethodParameterArray() { var output = new StringBuilder(); output.AppendLine(); Type t = typeof(API); foreach (var mi in t.GetMethods()) { var argsLine = new StringBuilder(); bool isFirst = true; argsLine.Append("object[] args = {"); var args = mi.GetParameters(); foreach (var pi in args) { if (isFirst) { isFirst = false; } else { argsLine.Append(", "); } argsLine.AppendFormat("{0}", pi.Name); } argsLine.AppendLine("};"); //close object[] initialiser output.AppendLine(argsLine.ToString()); output.AppendFormat("Log(\"{0}\",args);", mi.Name); output.AppendLine(); output.AppendLine(); } return output.ToString(); } </code></pre> <p>This code snippet loops through the methods on a class and outputs an object[] array initialised with the arguments passed into the method and a Log call containing the arguments and the method name.</p> <p>Example output:</p> <pre><code>object[] args = {username, password, name, startDate, endDate, cost}; Log("GetAwesomeData",args); </code></pre> <p>This block can then be pasted into the top of the method to achieve the required effect.</p> <p>It is more manual than I would have liked, but it is a lot better than having to type the parameters by hand and far less error prone.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
