Here's a couple more from my own project (MBG Extensions Library):

public static StringBuilder Append(this StringBuilder stringBuilder, params string[] values)
{
foreach (string value in values)
{
stringBuilder.Append(value);
}
return stringBuilder;
}
public static StringBuilder Append(this StringBuilder stringBuilder, params object[] values)
{
foreach (object value in values)
{
stringBuilder.Append(value);
}
return stringBuilder;
}

Maybe you will find them useful :-)
