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();
}
