WebService：

[System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService {

  public WebService () {

  //如果使用设计的组件，请取消注释以下行 
  //InitializeComponent(); 
  }

  [WebMethod]
  public string[] GetCompleteList(string prefixText, int count)
  {
  char c1, c2, c3;
  if (count == 0)
  count = 10;
  List<String> list = new List<string>(count);
  Random rnd = new Random();
  for (int i = 1; i <= count; i++)
  {
  c1 = (char)rnd.Next(65, 90);
  c2 = (char)rnd.Next(97, 122);
  c3 = (char)rnd.Next(97, 122);
  list.Add(prefixText + c1 + c2 + c3);
  }
  return list.ToArray();
  }
}
测试后网站正常，没有错误，但是和正常的文本框输入一样。
