是的呢，打算是由用户从文本框输入，输入什么，就增加到数据库里

string inStr = "insert into info (name,password,sex) values ('"+TextBox1.Text+"','"+TextBox2.Text+"','"+TextBox3.Text+"')"
cmd = New SqlCommand(inStr, con)
cmd.ExecuteNonQuery()

cmd = New SqlCommand("insert into info (name,password,sex) values ('" & myname &"' ,'" & mypassword & "' , '" & mysex & " ')", con)
