标题: 在ASP.NET中备份恢复Sql Server数据库
向大家介绍如何使用 ASP.NET 备份恢复 Sql Server 数据库,大家可以做个参考,也希望对大家有所帮助。  备份SqlServer数据库:
以下是引用片段:
  string SqlStr1 = "Server=(local);database=’" + this.DropDownList1.SelectedValue + "’;Uid=sa;Pwd=";  

  string SqlStr2 = "backup database " + this.DropDownList1.SelectedValue + " to disk=’" + this.TextBox1.Text.Trim() + ".bak’";  
  SqlConnection con = new SqlConnection(SqlStr1);  
  con.Open();  
  try  
  {  
  if (File.Exists(this.TextBox1.Text.Trim()))  
  {  
  Response.Write(" ");  
  return;  
  }  
  SqlCommand com = new SqlCommand(SqlStr2, con);  
  com.ExecuteNonQuery();  
  Response.Write(" ");  
  }  
  catch (Exception error)  
  {  
  Response.Write(error.Message);  
  Response.Write(" ");  
  }  
  finally  
  {  
  con.Close();  
  }  
  还原SqlServer数据库:
以下是引用片段:
  string path = this.FileUpload1.PostedFile.FileName; //获得备份路径及数据库名称  
  string dbname = this.DropDownList1.SelectedValue;  
  string SqlStr1 = "Server=(local);database=’" + this.DropDownList1.SelectedValue + "’;Uid=sa;Pwd=";  
  string SqlStr2 = "use master restore database " + dbname + " from disk=’" + path + "’";  
  SqlConnection con = new SqlConnection(SqlStr1);  
  con.Open();  
  try  
  {  
  SqlCommand com = new SqlCommand(SqlStr2, con);  
  com.ExecuteNonQuery();  
  Response.Write(" ");  
  }  
  catch (Exception error)  
  {  
  Response.Write(error.Message);  
  Response.Write(" ");  
  }  
  finally  
  {  
  con.Close();
