給出的Web服務器運行此這表明network path was not found錯誤。 請幫我解決這個問題。

public class Connection 
{ 
    public SqlConnection con = new SqlConnection("server=173.192.96.130;Initial Catalog=hrmodule;Integrated Security=false;user=hrmodule1;password=hrmodule@123"); 

    SqlConnection getconnection() 
    { 
     return con; 
    } 
    public void openconn() 
    { 
     **con.Open();** the error occur on this line 

    } 
    public void closeconn() 
    { 
     con.Close(); 
    } 

    public DataTable GetData(string query) 
    { 
     SqlDataAdapter da = new SqlDataAdapter(query, getconnection()); 
     DataTable dt = new DataTable(); 
     da.Fill(dt); 
     return dt; 
    } 
    public void Storepro(string sp, string[] pn, string[] pt, string[] pv, int nos) 
    { 
     SqlCommand cmd = new SqlCommand(sp, con); 
     cmd.CommandType = CommandType.StoredProcedure; 
     for (int i = 0; i < nos; i++) 
     { 
      switch (pt[i]) 
      { 
       case "string": 
        cmd.Parameters.AddWithValue(pn[i], pv[i]); 
        break; 
       case "int": 
        cmd.Parameters.AddWithValue(pn[i], Convert.ToInt32(pv[i])); 
        break; 
       case "decimal": 
        cmd.Parameters.AddWithValue(pn[i], Convert.ToDecimal(pv[i])); 
        break; 
       case "DateTime": 
        cmd.Parameters.AddWithValue(pn[i], Convert.ToDateTime(pv[i])); 
        break; 
      } 

     } 
     con.Open(); 
     cmd.ExecuteNonQuery(); 
     con.Close(); 
    }

在web.config中你

<connectionStrings> 
    <add name="ProjectConnectionString" connectionString="Data Source=173.192.96.130;Initial Catalog=hrmodule;Integrated Security=false;user=hrmodule1;password=hrmodule@123"/> 
</connectionStrings> 

在C＃頁面刪除

public SqlConnection con = new SqlConnection("server=173.192.96.130;Initial Catalog=hrmodule;Integrated Security=false;user=hrmodule1;password=hrmodule@123"); 

並添加

SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["ProjectConnectionString"].ToString());
