    <p>Why not use generic types? Define your class interface:</p> <pre><code> public interface IDynConcatenateString { string Concatenate(string s1, string s2); } </code></pre> <p>And then generate dinamic code</p> <pre><code> public T GetInstanceOf&lt;T&gt;(string code, string typename) { Console.WriteLine("Now doing some injection..."); Console.WriteLine("Creating injected code in memory"); CSharpCodeProvider codeProvider = new CSharpCodeProvider(); ICodeCompiler icc = codeProvider.CreateCompiler(); CompilerParameters parameters = new CompilerParameters(); parameters.GenerateExecutable = false; parameters.GenerateInMemory = true; //parameters.OutputAssembly = "DynamicCode.dll"; // if specified creates the DLL CompilerResults results = icc.CompileAssemblyFromSource(parameters, code); //type name = "CodeInjection.DynConcatenateString" T codeclass = (T)results.CompiledAssembly.CreateInstance(typename); return codeclass; } </code></pre> <p>Try to execute like this...</p> <pre><code>public void Exec() { string code = @" namespace CodeInjection { public class MyDynConcatenateString : IDynConcatenateString { public string Concatenate(string s1, string s2){ return s1 + "" ! "" + s2; } } }"; IDynConcatenateString writer = GetInstanceOf&lt;IDynConcatenateString&gt;( code, "CodeInjection.MyDynConcatenateString"); var s1 = Console.ReadLine(); var s2 = Console.ReadLine(); var result = writer.Concatenate(s1, s2); Console.WriteLine(result); } </code></pre> <p>The IDynConcatenateString implementation is dynamic, defined in the "code" variable, as a parameter of Exec method. You only need to define the interface, and no need to hardcode method names or class names.</p>

    1. COHave you tried compiling this? The problem remains: `MyDynConcatenateString` is a static class. As such it can't implement an interface and it can't be instantiated.

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).
