我很新，正在尝试创建一个 C# 程序，使用 FB API 从 Facebook 检索帖子。
我有一个字数统计功能，可以检查否定词词典。这意味着它将显示否定词及其出现频率。
我现在面临的问题是，我想显示包含这个负面词的帖子。但是，如果否定词在帖子中出现 3 次，则帖子会出现三次。我该如何解决这个问题？
Below is my code:
(For designer)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace empTRUST
{
public partial class PostAnalysis : Form
{
DBStatusDL ad;
string target_fbid;
public PostAnalysis(string target_fbid)
{
InitializeComponent();
this.target_fbid = target_fbid;
ad = new DBStatusDL();
}
private void button_Displayposts_Click(object sender, EventArgs e)
{
int i = 1;
var dir = new DirectoryInfo(Application.StartupPath + "\\Dictionary"); //Load the dictionary from debug folder
var ed = new matchingWordsWithPosts();
var rows = ad.LoadStatus(target_fbid); //Call the load status function based on fb_id
foreach (FileInfo file in dir.GetFiles()) //For loop, to loop through files
{
var dict = File.ReadAllLines(dir.FullName + "\\" + file);
foreach (var row in rows)
{
List<DataRow> words = ed.countWordsInStatus(row, dict); // Retrieves word dictionary returned from function
foreach (var word in words)
{
var item = new ListViewItem(new[] { i.ToString() ,word["Status_message"].ToString(), word["Status_time"].ToString() });
listViewPosts.Items.Add(item);
i++;
}
}
}
}
private void button_Back_Click(object sender, EventArgs e)
{
this.Close();
var abc = new AnalysisPage(target_fbid);
abc.Show();
}
}
}
(For class)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Data;
namespace empTRUST
{
class matchingWordsWithPosts
{
public List<DataRow> countWordsInStatus(DataRow status, string[] dictArray)
{
List<DataRow> statusList = new List<DataRow>();
var words = new Dictionary<string, int>(StringComparer.CurrentCultureIgnoreCase); // local word dictionary is created here
foreach (var dictEntry in dictArray)
{
var wordPattern = new Regex(@"\w+");
string smallDictEntry = dictEntry.ToLower();
foreach (Match match in wordPattern.Matches(status["Status_message"].ToString()))
{
if (match.ToString() == smallDictEntry)
{
statusList.Add(status);
}
}
}
return statusList; // returns local word dictionary to receiving end
}
}
}
