Why not take care of the first character before the loop, instead of checking it every time (not that it makes a big difference on modern hardware)? This also moves the char declaration out of the loop.private string createDisplayText(string propertyName){ if...
Why not take care of the first character before the loop, instead of checking it every time (not that it makes a big difference on modern hardware)? This also moves the char declaration out of the loop.
 
private string createDisplayText(string propertyName)
{
    if (String.IsNullOrEmpty(propertyName))
    {
        return String.Empty;
    }
 
    StringBuilder builder = new StringBuilder();
    char character = char.ToUpper(propertyName[0]);
    builder.Append(character);
 
    for (int i = 1; i < propertyName.Length; ++i)
    {
        character = propertyName[i];
        if (char.IsUpper(character))
        {
            builder.Append(" ");
        }
        builder.Append(character);
    }
 
    return builder.ToString();
}
 
This isn't really an alternate, as much as a minor modification.
 
Also, the for loop could be shorter, if somewhat less readable.
for (int i = 1; i < propertyName.Length; ++i)
{
    character = propertyName[i];
    builder.Append((char.IsUpper(character)) ? ' ' + character : character);
}
