在 IIS 7 中部署 ASP.NET 应用程序时，出现错误：
Server Error in '/' Application
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
异常详细信息：System.IndexOutOfRangeException：找不到表 0。
Source Error:
Line 46: dsDesignation= GetChartData("select * from LHSDesignation");
Line 47:

Line 49: {

Source File: D:\Raji\LHS\LHS\Chart.aspx.cs Line: 48
Stack Trace:

页面加载的代码是：
protected void Page_Load(object sender, EventArgs e)
{
string tmpDesignation = string.Empty;
conString =Convert.ToString(ConfigurationManager.AppSettings["conString"]);
strDesignation = Convert.ToString(ConfigurationManager.AppSettings["Designation"]);
conection = new SqlConnection(conString);
if (HttpContext.Current.Session["UserLogin"] != null)
{
ClientScript.RegisterStartupScript(this.GetType(), "", "$.prompt('Please login to Update Score')", true);
}
dsDesignation= GetChartData("select * from LHSDesignation");
if (dsDesignation != null && dsDesignation.Tables[0].Rows.Count > 0)
{
foreach (DataRow dr in dsDesignation.Tables[0].Rows)
{
dnDesignatin.Add(Convert.ToString(dr["DesignationName"]), Convert.ToString(dr["TargetScore"]));
}
}
请帮助我解决此错误 在 IIS 7 中运行需要做什么？
