我希望使用foreach循环从项目列表中创建这些按钮,以访问存储在这些项目中的信息。
我使用foreach循环从一个目录中的一系列代表文件的项创建按钮,这些项包含指向这些文件的链接。我的目标是使按下这些按钮打开一个包含这些文件的对话框,以便在其中写入一行。
public List<mov.Movie> movies = new List<mov.Movie>() { };
private void writeReportToolStripMenuItem_Click(object sender, EventArgs e)
{
foreach (string file in Directory.EnumerateFiles(@"C:\Users\sloup\OneDrive\Desktop\MovieList", "*.txt"))
{
var lines = File.ReadAllLines(file);
string movieName = lines[0];
if (movies.Select(x => x.Name).Contains(movieName))
{
}
else
{
string movieLength = lines[1];
string movieYear = lines[2];
string movieReport = lines[3];
movies.Add(new mov.Movie(movieName, movieLength, movieYear, movieReport, @"C:\Users\sloup\OneDrive\Desktop\MovieList" + movieName + ".txt"));
}
}
int X = 1;
int Y = 1;
foreach (var movie in movies)
{
var movie1Button = new Button();
movie1Button.Text = movie.Name;
movie1Button.Font = new Font("Calibri", 12);
movie1Button.ForeColor = Color.Black;
movie1Button.Padding = new Padding(6);
movie1Button.AutoSize = true;
this.Controls.Add(movie1Button);
movie1Button.Location = new System.Drawing.Point(20, 50 * X);
X++;
movie1Button.Click += Movie1Button_Click;
var movie1Label = new Label();
movie1Label.Text = movie.Year;
movie1Label.Font = new Font("Calibri", 12);
movie1Label.ForeColor = Color.Black;
movie1Label.Padding = new Padding(6);
movie1Label.AutoSize = true;
this.Controls.Add(movie1Label);
movie1Label.Location = new System.Drawing.Point(200, 50 * Y);
Y++;
}
}
private void Movie1Button_Click(object? sender, EventArgs e)
{
string[] lines1 = File.ReadAllLines();
var lines = File.ReadAllLines();
string movieName = lines[0];
string movieLength = lines[1];
string movieYear = lines[2];
}
public class Movie
{
public string Name;
public string Length;
public string Year;
public string Report;
public string Link;
public Movie(string movieName, string movieLength, string movieYear, string movieReport, string movieLink)
{
Name = movieName;
Length = movieLength;
Year = movieYear;
Report = movieReport;
Link = movieLink;
}
}
