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(); 
  }
