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>");
