Group cannot be found

Question

I am getting error Group cannot be found when I use following code:

string group = GetGroupName("1");  
SPUser user = web.SiteGroups[group].Users.GetByID(SPContext.Current.Web.CurrentUser.ID);

But strangely following code works fine:

string group = "Marketing";  
SPUser user = web.SiteGroups[group].Users.GetByID(SPContext.Current.Web.CurrentUser.ID);

The method GetGroupName is a static method that returns a string "Marketing". I don't know why it is not working in case1 but works in case2. I have checked hundred of times that the string returned by function is "Marketing" without any space or any other extra character.

Any idea why this is happening?

We can add the method below to solve this issue.

static string GetRichTextValue(string value)
{
    if (null == value)
    {
        return string.Empty;
    }
    StringBuilder sb = new StringBuilder(value.Length);
    foreach (char c in value)
    {
        if (char.IsLetterOrDigit(c) || char.IsPunctuation(c))
        {
            sb.Append(c);
        }
    }
    return sb.ToString();
}

Then get group name using the following line of code.

string group = GetRichTextValue(GetGroupName("1"));
