c# - 如何将 List<> 绑定(bind)到 dataGridview C#

Question

我是窗口应用程序的新手。
我编写了一个代码来读取文件夹中的文件并逐行读取它并找到一些字符串并将其计数显示到 dataGridView。

我想填充一个不起作用的 dataGridview。
我在互联网上尝试了不同的方法，但都没有用。

我知道我可能犯了一个愚蠢的错误。
我的代码如下

  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";
        //}
    }

数据绑定(bind)仅适用于设置/获取属性，不适用于公共(public)字段。

尝试像这样更改您的 FileDetail :

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