List, strings and vs Template

I'm having a list of strings whit some values and I want to make some kind of variable for keeping code that I will be using in template file.

For example lets say I have list with this 3 string values: configService, scaleCoefConfigService, sessionService. Name of the list is chItemName.

And I need to generate this kind of code that I will parse later into template: 

[Dependency("configService")]

[Dependency("scaleCoefConfigService")]

[Dependency("sessionService")]

So my question is can make some variable and mechanism for iterating thou list of strings that adds every single item from list to variable?

I've tried this:

foreach (var tp in controllerChecked)
{
   var genCode = "[Dependency](" '"'  + chItemName + '"'")] \n"
}

controllerChecked is collection of objects and one of the objects value is Name that I'm getting like this:

var chItemName = controllerChecked.Select(c => c.Name).ToList();

This is how the list chItemName is getting those strings.

But of course it is impossible to use + with lists and this kind of stuff will never work. Someone has better idea?

This worked perfectly good. I have little bit harder version of this, if you can figure out how to do this:

Lets say that instead of one chItemName list I have 2 more: fName and chItemType, both are string lists.

And I have to generate this kind of code:

[Dependency("alarmsService")]
public IAlarmsService AlarmsService { get; set; }

[Dependency("jsonFactory")]
public IJSONFactoryService JsonFactory { get; set; }

[Dependency("dataBean")]
public IDataBean DataBean { get; set; }

alarmsServise, jsonFactory and dataBean are items of chItemName. IAlarmsService, IJSONFactoryService and IDataBean are items of chItemType. AlarmsService, Json Factory and DataBean are items of fName list.

fName is list that I got from chItemType by trimming the first letter from each string in list:

List<string> fName = new List<string>();
foreach(var i in chItemType)
{
    var newName = i.Remove(0,1);
    fName.Add(newName);
}

So only that list is not a part of controllerChecked list. The othere two are defined like this:

var chItemType = controllerChecked.Select(c => c.Type).ToList();
var chItemName = controllerChecked.Select(c => c.Name).ToList();

Can I edit foreach somehow or maybe I can make parts of code with StringBulider and after that merged them together?

In your example, you are not using the tp variable, which contains will contain each of the values within controllerChecked, one at a time.

You could just iterate through the chItemName list and add the result to a StringBuilder:

StringBuilder codeBuilder = new StringBuilder();
foreach (string tp in chItemName)
{
    codeBuilder.AppendLine("[Dependency(\"" + tp + "\")]");
}

string code = codeBuilder.ToString();

If controllerChecked contains more information, you could also directly access it:

StringBuilder codeBuilder = new StringBuilder();
foreach (var item in controllerChecked)
{
    string propertyName = item.Name.SubString(1);

    codeBuilder.AppendLine("[Dependency(\"" + item.Name + "\")]");
    codeBuilder.AppendLine("public " + item.Type + " " + propertyName + " { get; set; }");
    codeBuilder.AppendLine();
}

string code = codeBuilder.ToString();

PS. I would definitely change the name of chItemName to chItemNames as it is a list, but that is up to you of course.
