You have several things incorrect with your code, honestly it is horrible. This what it should be
string info = @"G\F\3\6\H\Y";
List<label> labels = new List<label>();
string[] split = info.Split(new char[] {'\\'});
for(int x = 0; x < split.Length; x++)
{
labels[x].Text = split[x];
}</label></label>
