首先我们先分析ASP备份SQL数据库的代码，详细如下：
备份SqlServer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("");
return;
}
SqlCommand com = new SqlCommand(SqlStr2, con);
com.ExecuteNonQuery();
Response.Write("");
}
catch (Exception error)
{
Response.Write(error.Message);
Response.Write("");
}
finally
{
con.Close();
}
下面是ASP.NET还原SQL数据库的方法，代码如下：
还原SqlServer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("");
}
catch (Exception error)
{
Response.Write(error.Message);
Response.Write("");
}
finally
{
con.Close();
}
