将项目添加到radlistbox

Question

我想从FileInfo添加项目到我的RadListBox，虽然我不能，我试图将文件转换成RadListBoxItem对象，但我得到的错误，它不能将字符串转换为radlistboxitem。有人可以点亮一下吗？谢谢。

   DirectoryInfo dir = new DirectoryInfo(Path.GetFullPath(fp)); 
       lb_Files.Items.Clear(); 
       foreach (FileInfo file in dir.GetFiles()) 
       { 
        RadListBoxItem rlb = new RadListBoxItem(); 
        rlb = (RadListBoxItem)file.ToString(); 
        //radListBox 
        lb_Files.Items.Add(rlb.ToString()); 
       } 

Answer 1

试试这个

DirectoryInfo dir = new DirectoryInfo(Path.GetFullPath(fp)); 
lb_Files.Items.Clear(); 
foreach (FileInfo file in dir.GetFiles()) 
{ 
    lb_Files.Items.Add(new RadListBoxItem(file.ToString(), file.ToString())); 
} 

Answer 2

不，你不能投了String对象到RadListBoxItem，你必须使用字符串作为你的价值和Text属性创建RadListBoxItem：

所以替换此：

RadListBoxItem rlb = new RadListBoxItem(); 
rlb = (RadListBoxItem)file.ToString(); 
//radListBox 
lb_Files.Items.Add(rlb.ToString()); 

有了这个：

lb_Files.Items.Add(new RadListBoxItem 
{ 
    Value = file.ToString(), 
    Text = file.ToString() 
});
