Solved Storing a list in a config file?

I has created the config file and GetConfig, more the moment I add a list in GetConfig, this error occurs, as you can see below:

Code:

(InvalidCastException: Value is not a convertible object: System.Collections.Generic.List`1[System.Object] to System.Collections.Generic.List`1[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]])

My config:

Code:

List<string> help1 = new List<string>(new string[]{
            "Use <color=orange>/list info</color>",
                        "Use <color=orange>/list info1</color>"
        });
void LoadDefaultConfig()
{
     Config["Comandos da lista de ajuda 1"] = help1 = GetConfig("Comandos da lista de ajuda 1", help1);
}
T GetConfig<T>(string name, T value) => Config[name] == null ? value : (T)Convert.ChangeType(Config[name], typeof(T));

Why does this error occur?
How to solve ?

 

There is no method that can get a List <string> configuration?

 

Poderia me dar um exemplo?
I'll be very grateful
[DOUBLEPOST=1523318473][/DOUBLEPOST]I'm trying this, because whenever my plugin reloads, the setting goes back to the default

 

Code:

var x = string.Join ("\n", myList.ToArray());
var z = string.Concat("", x);
SendReply(player, z);

How do I do this with a List <object>?

 

How to include the config in a dictionary ?
Ex my config:

Code:

string chat prefix = "example";
void LoadDefaultConfig()
{
     Config["Settings"] = new Dictionary<string, object>{
            Config["Chat prefix"] = chatprefix = GetConfig("Chat prefix", chatprefix);
      };
}T GetConfig<T>(string name, T value) Config[name] == null ? value : (T)Convert.ChangeType(Config[name], typeof(T));

This code sends an error

 

Remove the space between chat and prefix, in your first line
