AutoComplete.asmx
代碼如下:
<%@ WebService Language="C#" CodeBehind="~/App_Code/AutoComplete.cs" Class="AutoComplete" %>

//如果使用設計的組件，請取消注釋以下行
//InitializeComponent();
}
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
//獲得景區
[WebMethod]
public string[] GetScenic(string prefixText,int count)
{
ET_ERP.BLL.ERP_ScenicArea b_ScenicArea = new ET_ERP.BLL.ERP_ScenicArea();
string strWhere = " SA_Name like '" + prefixText + "%' AND SA_IsDel = 0";
DataSet ds = b_ScenicArea.Select(" top "+count+" SA_Name", strWhere);
count = ds.Tables[0].Rows.Count;
string[] array = new string[count];
for (int i = 0; i < count; i++)
{
array[i] = ds.Tables[0].Rows[i]["SA_Name"].ToString();
}
return array;
}
}
