即使使用 dispose 函数，当前可执行文件正在使用文件

Question

这是我的代码，我试图用另一个文件夹中的另一个图像替换一个文件夹中的图像，同时保留他的文件名。我正在使用 dataGridView 检索文件夹的内容我正在将所选单元格中的图像直接加载到 picturebox 我在用着： File.Copy(Source, Destination,true); 为了复制我的文件，我确保处理掉所有东西，这样它就不会被进程使用。

我的完整项目（评论）：

private void Form1_Load(object sender, EventArgs e)
{
    //Get content of the DESTINATION files on a specific folder and put it into a dataGridView1

    string[] files = Directory.GetFiles(@Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\Black Desert\FaceTexture", "*", SearchOption.TopDirectoryOnly);
    DataTable table = new DataTable();
    table.Columns.Add("File Name");
    for (int i = 0; i < files.Length; i++)
    {
        FileInfo file = new FileInfo(files[i]);
        table.Rows.Add(file.Name);

    }
    dataGridView1.DataSource = table;

    //Get content of the SOURCE files on a specific folder and put it into a dataGridView2

    string[] files2 = Directory.GetFiles(@"Face Texture", "*");
    DataTable table2 = new DataTable();
    table2.Columns.Add("File Name");
    for (int i = 0; i < files2.Length; i++)
    {
        FileInfo file = new FileInfo(files2[i]);
        table2.Rows.Add(file.Name);

Answer 1

您想处理图像对象而不是 PictureBox 对象。

因此pictureBox.Image.Dispose()将解决问题。

所以 PictureBox has image 属性 class 有一个 Dispose() 方法

即使使用 dispose 函数，当前可执行文件正在使用文件

File is being used by the current executable even though using dispose function

.net

c#
