下面就是我写的一个DataSet方法
public DataSet DisCustLanguage(string fst_language)
{
SqlConnection myConn=new SqlConnection(Connstr.ConnectionString);
DataSet ds = new DataSet();
try
{
SqlDataAdapter command = new SqlDataAdapter("Display_Cust_languages", myConn);
command.SelectCommand.CommandTimeout = 1000;
command.Fill(ds, "ds");
SqlParameter Param;
Param=new SqlParameter("@fst_language",SqlDbType.NVarChar,50);
Param.Value=fst_language;
mycmd.Parameters.Add(Param);
mycmd.CommandType=CommandType.StoredProcedure;
}
catch (System.Data.SqlClient.SqlException e)
{
throw(e);
}
finally
{
if(myConn.State==ConnectionState.Open)
{
myConn.Close();
}
}
return ds;
}
上面就是我所写的方法,现在的问题是不知道如何在存储过程中所需的参数传进去
报错:过程 'Display_Cust_languages' 需要参数 '@fst_laguage',但未提供该参数。
谢谢大家了!
------解决方案--------------------------------------------------------
楼主写的有点问题,我修改了一下:
- C# code
public DataSet DisCustLanguage(string fst_language) { SqlConnection myConn=new SqlConnection(Connstr.ConnectionString); DataSet ds = new DataSet(); try { SqlCommand command =new SqlCommand("Display_Cust_languages", myConn);command.CommandType=CommandType.StoredProcedure; SqlParameter Param; Param=new SqlParameter("@fst_language",SqlDbType.NVarChar,50); Param.Value=fst_language; command.Parameters.Add(Param);myConn.Open();SqlDataAdapter myda = new SqlDataAdapter();myda.SelectCommand=commandmyda.SelectCommand.CommandTimeout = 1000;myda.Fill(ds, "ds");} catch (System.Data.SqlClient.SqlException e) { throw(e); } finally { if(myConn.State==ConnectionState.Open) { myConn.Close(); } } return ds; }
