folderbrowserdialog訪問路徑無效

Question

每次我運行該程序時，都有一個錯誤，表示訪問路徑被拒絕。我已經檢查允許所有用戶的文件夾，取消選中只讀，仍然不會工作

private void button2_Click(object sender, EventArgs e) 
{ 
    try 
    { 
     FolderBrowserDialog fbd = new FolderBrowserDialog(); 
     DialogResult result = fbd.ShowDialog(); 
     string[] files = Directory.GetFiles(fbd.SelectedPath); 
     textBox2.Text = fbd.SelectedPath; 
    } 
    catch (Exception ex) 
    { 
      MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); 

    } 
} 

Answer 1

添加支票結果。

DialogResult result = fbd.ShowDialog(); 
if (result == DialogResult.OK) 
{ 
    string[] files = Directory.GetFiles(fbd.SelectedPath); 
    textBox2.Text = fbd.SelectedPath; 
} 

Answer 2

    try 
    { 
     FolderBrowserDialog fbd = new FolderBrowserDialog(); 
     DialogResult result = fbd.ShowDialog(); 
     textBox2.Text = (result == DialogResult.OK) ? fbd.SelectedPath : string.Empty; 
    } 
    catch (Exception ex)
