ASP.NET备份、还原SQL Server数据库
一、备份SQL Server数据库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(''此文件已存在，请从新输入！'');location=''Default.aspx''</script>");return;
}
SqlCommand com = new SqlCommand(SqlStr2, con);
com.ExecuteNonQuery();
Response.Write("<script language=javascript>alert(''备份数据成功！'');location=''Default.aspx''</script>");
}
catch (Exception error)
...{
Response.Write(error.Message);Response.Write("<script language=javascript>alert(''备份数据失败！'')</script>");
}
finally
...{
con.Close();
} 二、还原SQL Server数据库
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("<script language=javascript>alert(''还原数据成功！'');location=''Default.aspx''</script>");
}
catch (Exception error)
...{
Response.Write(error.Message);Response.Write("<script language=javascript>alert(''还原数据失败！'')</script>");
}
finally
...{
con.Close();
}
