如何將List <>綁定到dataGridview C＃

Question

我是窗口應用程序的新手。
我編寫了一個代碼來讀取文件夾中的文件並逐行讀取並找到一些字符串並將其計數顯示給dataGridView。

我想填充一個無效的dataGridview。
我在互聯網上嘗試了不同的方法，但沒有一種方法有效。

我知道我可能犯了一個愚蠢的錯誤。
我的代碼如下

  public class FileDetail
    {
        public  string filename;
        public int openConnectionCount;
        public int closeConnectionCount;
    }


    private void button1_Click(object sender, EventArgs e)
    {
        int openConnectionCount = 0;
        int closeConnectionCount = 0;
        List<FileDetail> fileDetails =new List<FileDetail>();
        foreach (string file in Directory.EnumerateFiles(textBox1.Text, "*.*", SearchOption.AllDirectories))
        {
            FileDetail fileDetail =new FileDetail();
            fileDetail.filename = file;
            // Read the file as one string.
            using (StreamReader myFile = new StreamReader(file))
            {

                string line;
                while ((line = myFile.ReadLine()) != null)
                {
                    if (line.Contains(" OpenConnection()")) openConnectionCount++;
                    if (line.Contains(" CloseConnection()")) closeConnectionCount++;
                }
                fileDetail.openConnectionCount = openConnectionCount;
                fileDetail.closeConnectionCount = closeConnectionCount;
            }
            fileDetails.Add(fileDetail);
            openConnectionCount = 0;
            closeConnectionCount = 0;
        }



        dataGridView1.AutoGenerateColumns = false;

        dataGridView1.Columns.Add("filename", "File Name");
        dataGridView1.Columns.Add("openConnectionCount", "Open Connection");
        dataGridView1.Columns.Add("closeConnectionCount", "close Connection");

        dataGridView1.Columns[0].DataPropertyName = "filename";
        dataGridView1.Columns[1].DataPropertyName = "openConnectionCount";
        dataGridView1.Columns[2].DataPropertyName = "closeConnectionCount";

        var filenamesList = new BindingList<FileDetail>(fileDetails); // <-- BindingList
        dataGridView1.DataSource = filenamesList;


        //dataGridView1.DataSource = fileDetails;




        //dataGridView1.b

        //foreach (var fileDetail in fileDetails)
        //{
        //    label1.Text += "FileName:=" + fileDetail.filename + "\t Open Connection:= " +
        //                   fileDetail.openConnectionCount + "\t close connection:=" +
        //                   fileDetail.closeConnectionCount+"\n";
        //}
    }

Answer 1

數據綁定僅適用於“設置/獲取屬性”，而不適用於公共字段。

嘗試像這樣更改FileDetail ：

public class FileDetail
{
    public  string filename { get; set; }
    public int openConnectionCount { get; set; }
    public int closeConnectionCount { get; set; }
}

Answer 2

如果要自動生成datagridview列，則可以將其用作

public class FileDetail
{
    [DisplayName("File Name")]    
    public  string filename { get; set; }
    [DisplayName("Open Connection")]    
    public int openConnectionCount { get; set; }
    [DisplayName("close Connection")]    
    public int closeConnectionCount { get; set; }
}

您可以使用List作為數據源，而不使用Binding源

dataGridView1.DataSource = fileDetails.ToArray();
