using (SqlConnection conn = new SqlConnection(connectionString))
{
//string sql1 = "insert into Usertable(Username,name,Upassword,Umoney) values(@Username,@name,@Upassword,@Umoney)";
conn.Open();
try
{
SqlCommand cmd = new SqlCommand("insert into Usertable(Username,name,Upassword,Umoney) values('11','11','11',12)", conn);
cmd.ExecuteNonQuery();
conn.Close();
MessageBox.Show("添加成功");
}
catch (Exception err)
{
MessageBox.Show(err.Message);
} 展开
