c＃中的网络服务代码在vb中使用它
public string[] GetCompletionList(string prefixText, int count)
{
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\Vinu\\My Documents\\Northwind.mdb");
String instr = prefixText + "%";
OleDbDataAdapter da = new OleDbDataAdapter("select ContactName from Customers where ContactName like '"+instr+"'", conn);
DataTable dt=new DataTable();
da.Fill(dt);
List<string> items = new List<string>(count);
for(int i=0;i<dt.Rows.Count;i++)
{
items.Add(dt.Rows[i].ItemArray[0].ToString());
}
return items.ToArray();
}

IT已经解决了感谢GOD ...特别感谢@Vinod和@Neha
问题出在AutoComplete.asmx
<%@ WebService Language="vb" CodeBehind="AutoComplete.asmx.vb" Class="attend.AutoComplete" %>
Class="attend.AutoComplete" ...参加是我采用AutoComplete.asmx和我的
项目名称是PMS ..我将其更改为：
<%@ WebService Language="vb" CodeBehind="AutoComplete.asmx.vb" Class="PMS.AutoComplete" %>
现在工作正常..
再次感谢大家...... @ Vinod和@Neha
