C#执行带参数的存储过程一个事例

private void btnCheck_Click(object sender, EventArgs e)
{
SqlConnection conn = sqlhelper.getcon();
conn.Open();
SqlCommand cmd;
cmd = new SqlCommand("P_Test_ClientBookDetail2", conn);
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter[] param ={ new SqlParameter("@ClientCode", SqlDbType.VarChar, 50),
new SqlParameter("@ClientName", SqlDbType.VarChar, 50),
new SqlParameter("@Check", SqlDbType.VarChar, 20)};
param[0].Value = cboxShop.SelectedValue.ToString();
param[1].Value = cboxShop.Text.Trim().ToString();
if (cboxAllShow.Checked)
{
param[2].Value = "Yes";
}
else
{
param[2].Value = "No";
}

//cmd.Parameters.Add(param);
foreach (SqlParameter parameter in param)
{
cmd.Parameters.Add(parameter);
}
SqlDataAdapter sqlda = new SqlDataAdapter(cmd);
DataSet myds = new DataSet();

sqlda.Fill(myds);

System.Data.DataTable dt = myds.Tables[0];
this.gridControl1.DataSource = dt;
//gridView1.BestFitColumns();//自动按内容调整列
}
