大家早上好, 我試圖提取使用此代碼SGML文件,但我得到空文件,結果,這是我的Python代碼: from os import listdir
from os import makedirs
from os.path import isfile, join
from re import sub
import ast
import numpy
import xml.etree.Eleme
全HTML文檔我試圖用GetStringAsync using (var client = new HttpClient())
{
var html = await client.GetStringAsync(url);
richTextBox1.Text = html.ToString();
}
和DownloadString System.Net.WebClient
我想執行這個查詢: INSERT INTO [Order] (FactorId, ProductId, Entity)
VALUES((SELECT Top 1 FactorId FROM Factor WHERE UserId = @UserId AND Status = -1), @ProductId, @Entity)
但出現以下錯誤: 子查詢在此背景下 允許。只有標量表達式允許使用
