ASP.NET備份恢複SQL Server資料庫

一、備份SQL Server資料庫

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("<script language=javascript>alert('此檔案已存在，請從新輸入！'); location='Default.aspx'</script>"); return; } SqlCommand com = new SqlCommand(SqlStr2, con); com.ExecuteNonQuery(); Response.Write("<script language=javascript>alert('備份資料成功！'); location='Default.aspx'</script>"); } catch (Exception error) { Response.Write(error.Message); Response.Write("<script language=javascript>alert('備份資料失敗！')</script>"); } finally

二、還原SQL Server資料庫

string path = this.FileUpload1.PostedFile.FileName; //獲得備份路徑及資料庫名稱 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("<script language=javascript>alert('還原資料成功！'); location='Default.aspx'</script>"); } catch (Exception error) { Response.Write(error.Message); Response.Write("<script language=javascript>alert('還原資料失敗！')</script>"); } finally
