POIs there a way to get field name including class containing it and another class containing this class if field passed into function as object?
 

Note that there are some explanatory texts on larger screens.

    <p>I doing next thing... I pass into some function the field of some controls, like:</p> <pre><code>class ScenarioSelector { public ScenarioSelector() { SubjectInfo.SetStr(lbl_labs_header.Text); } } class SubjectInfo { public static void SetStr(object obj) { string name = obj.GetType().Name; string full_name = obj.GetType().FullName; Type t = obj.GetType(); //FieldInfo fi = FieldInfo.GetFieldFromHandle(/*I don't have any handle here*/); //Somehow understand that passed object is... "ScenarioSelector.lbl_labs_header.Text" and set it's value depending from it. } } </code></pre> <p>Function SetStr should understand the field name of passed object and set it's value depending of it's name. I tried something, but can't get what I need, I only getting System.String as name. <img src="https://i.stack.imgur.com/Lvy1L.png" alt="enter image description here"></p> <p>Whole idea behind that is interface translation. I want to store in file something like: <strong>[ScenarioSelector.lbl_labs_header.Text][TEXT_ON_THIS_LABEL]</strong> And easy set it by calling function <strong>SetStr</strong></p> <p>Maybe you have some ideas of how to make it another way or fix my way?</p> <p>P.S. Based on <strong>Medinoc</strong> example I did this:</p> <pre><code>static void Test3&lt;T&gt;(Expression&lt;Func&lt;T&gt;&gt; exp) { Expression body = exp.Body; List&lt;string&gt; memberNames = new List&lt;string&gt;(); MemberInfo previousMember = null; while(body.NodeType == ExpressionType.MemberAccess) { MemberExpression memberBody = (MemberExpression)body; string memberName = memberBody.Member.Name; if (previousMember == null) //this is first one { switch (memberBody.Member.MemberType) { case MemberTypes.Field: ((FieldInfo)memberBody.Member).SetValue(/*How to get the object instance?*/, "some_val"); break; case MemberTypes.Property: break; default: break; } } if (memberBody.Expression.NodeType == ExpressionType.Constant &amp;&amp; previousMember != null) //If it's the 'last' member, replace with type memberName = previousMember.DeclaringType.Name; memberNames.Add(memberName); previousMember = memberBody.Member; body = memberBody.Expression; } memberNames.Reverse(); Console.WriteLine("Member: {0}", string.Join(".", memberNames)); } </code></pre> <p>But still don't know how to get instance of object to set needed value.</p>

    1. COTo me it looks like your `obj` is a simple `string` and its *content* is what you show in the screenshot. So even when you would change the variable name, the content would still be the same.

    2. COIt is possible to pass by ref, but the problems is still how to get it's name.

    3. COMaybe you can if you pass a lambda expression returning the field (`SetStr(() => lbl_labs_header.Text)`) instead of the field itself. Your SetStr method will need to be changed to accept a lambda expression, though.

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.
