我试图在标签中显示 SQL 查询结果,但它没有显示。这是我的代码:
string result = "SELECT ACTIVE FROM [dbo].[test] WHERE ID = '" + ID.Text + "' ";
SqlCommand showresult = new SqlCommand(result, conn);
conn.Open();
showresult.ExecuteNonQuery();
string actresult = ((string)showresult.ExecuteScalar());
ResultLabel.Text = actresult;
conn.Close();
需要帮助请。谢谢!
试试这个。
string result = "SELECT ACTIVE FROM [dbo].[test] WHERE ID = '" + ID.Text + "' ";
SqlCommand showresult = new SqlCommand(result, conn);
conn.Open();
ResultLabel.Text = showresult.ExecuteScalar().ToString();
conn.Close();
