请各位快点帮忙啊！

为什用如下代码，打不开本发库呢？
try
{
conn = new SqlConnection(@"Data Source=(local);Integrated Security=SSPI;Initial Catalog=callersystems");
conn.Open();

adapter = new SqlDataAdapter("select * from equip_primaryInformation",conn);
data=new DataSet();
this.adapter.Fill(data,"equips");
this.datagird1.DataSource = data;
this.datagird1.DataMember = "equips";
this.datagird1.DataBind();
}
catch(Exception ex)
{

Response.Write(ex.Message  ); }
