如何使用C＃将多个参数传递给Crystal报表 [英] How Do I Pass The Multiple Parameters To Crystal Report Using C#

问题描述

我有以下代码将我的参数传递给水晶报告我在两天前工作正常但是现在它给我一个错误如下

索引无效。 （HRESULT异常：0x8002000B（DISP_E_BADINDEX））

我的代码是

 DateTime fdt = dateTimePicker1.Value.Date; 
 DateTime edt = dateTimePicker2.Value.Date; 
 DateTime from_date = dateTimePicker1.Value.Date; 
 DateTime to_date = dateTimePicker2.Value.Date; 
 string fdate = fdt.ToShortDateString（）; 
 string edate = edt.ToShortDateString（）; 
 
 if（fdt> = edt）
 {
 MessageBox.Show（To Date应该大于Date ..！）; 
} 
 else 
 {
 int user_id = TempDataStorage.userid; 
 DatabaseConnection cs = new DatabaseConnection（）; 
 Object o = cs.GetAfield（从App_User中选择branch_code，其中app_user_id =+ user_id +）; 
 branch_code = o.ToString（）; 
 
 
 string qry =从Balance_details选择opening_bal，其中sysdate =＃+ fdate +＃and branch_code ='+ branch_code +'; 
 OleDbCommand cmd1 = new OleDbCommand（qry，con）; 
 con.Open（）; 
 Object retvalue = cmd1.ExecuteScalar（）; 
 opening_bal = Convert.ToInt32（retvalue是DBNull？0：retvalue）; 
 con.Close（）; 
 
 string qry2 =从Balance_details选择closing_bal，其中sysdate =＃+ edate +＃and branch_code ='+ branch_code +'; 
 OleDbCommand cmd2 = new OleDbCommand（qry2，con）;

请帮我解决此错误

解决方案

我也解决了这个问题我创建参数 水晶报告和我将该参数传递给水晶报告
 在上面我只是拼错参数名称我更正了 我自己

I have a following code with me to pass the parameters to a crystal report i was working fine before two days but now it give me an error as follows

Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

Please Help Me to solve this error

解决方案

I solved this question also i create a parameter in crystal report and i pass that parameter to the crystal report
In above i just miss spell the parameter name i correct it for myself
