asp.net调用存储过程的疑问
存储过程如下： 
create proc sp_InsertUsers 
@name varchar(20), 
@password varchar(20), 
@age int 
as 
insert into users values(@name,@password,@age) 

asp.NET调用如下: 

  string name = TextBox1.Text.Trim(); 
  string password = TextBox2.Text.Trim(); 
  int age = Convert.ToInt32(TextBox3.Text.Trim().ToString()); 

  using (coon=DataBase.getCon())//数据库链接 { 
  coon.Open(); 
  adapter = new SqlDataAdapter(); 
  adapter.SelectCommand=new SqlCommand(); 
  adapter.SelectCommand.Connection=coon; 
  adapter.SelectCommand.CommandText = "sp_InsertUsers('name','password',age)";//传入参数 
  adapter. SelectCommand.CommandType = CommandType.StoredProcedure; 
  代码正常执行，但是数据始终进不了数据库。这种直接传入参数的写法我第一次用，希望高手帮忙。

------解决方案--------------------

C# code

 adapter.InsertCommand=new SqlCommand(); 
            adapter.InsertCommand.Connection=coon; 
            adapter.InsertCommand.CommandText = "sp_InsertUsers('name','password',age)";//传入参数 
          adapter. InsertCommand.CommandType = CommandType.StoredProcedure;
adapter.InsertCommand.ExecuteNonQuery();
