Perhaps use an ArrayEditor for the string[]

<pre><code>public class Settings
{
 [EditorAttribute(typeof(System.ComponentModel.Design.ArrayEditor), typeof(System.Drawing.Design.UITypeEditor))]
 public string[] FileNames { get ; set; }
}
</code></pre>

Okay, this is how it works... 

<pre><code>public class FileNamesEditor : UITypeEditor
{
 private OpenFileDialog ofd;
 public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
 {
 return UITypeEditorEditStyle.Modal;
 }
 public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
 {
 if ((context != null) &amp;&amp; (provider != null))
 {
 IWindowsFormsEditorService editorService =
 (IWindowsFormsEditorService)
 provider.GetService(typeof(IWindowsFormsEditorService));
 if (editorService != null)
 {
 ofd = new OpenFileDialog();
 ofd.Multiselect = true;
 ofd.Filter = "Word|*.docx|All|*.*";
 ofd.FileName = "";
 if (ofd.ShowDialog() == DialogResult.OK)
 {
 return ofd.FileNames;
 }
 }
 }
 return base.EditValue(context, provider, value);
 }
}
</code></pre>

blocks|key|608499|text|原来的代码对我来说是有效的，除了需要重新排序。您需要在更改之前调用base.Initialize，否则它们会被覆盖(调试会很好地显示出来)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|608500|public+class+FileNamesEditor+:+FileNameEditor
{

}|code-block|syntax|javascript|608501|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The original code worked for me, except for a needed re-ordering. You need to call the base.Initialize before your changes, or they get overwritten (debugging will show it nicely)

<pre><code>public class FileNamesEditor : FileNameEditor
{
 protected override void InitializeDialog(OpenFileDialog openFileDialog)
 {
 base.InitializeDialog(openFileDialog);
 openFileDialog.Multiselect = true;
 openFileDialog.Filter = "Word|*.docx|All|*.*";
 }
}
</code></pre>

I want to implement a custom FileNameEditor; I want to set my own filter and I want to be able to select multiple files. 

<pre><code>public class Settings
{
 [EditorAttribute(typeof(FileNamesEditor), typeof(System.Drawing.Design.UITypeEditor))]
 public string FileNames { get; set; }
}

public class FileNamesEditor : FileNameEditor
{
 protected override void InitializeDialog(OpenFileDialog openFileDialog)
 {
 openFileDialog.Multiselect = true;
 openFileDialog.Filter = "Word|*.docx|All|*.*";
 base.InitializeDialog(openFileDialog);

 }
}
</code></pre>

This ignores the filter property and although I am able to select multiple files I can't assign them to my Settings.FileNames property because Settings.FileNames is of type string[] and the result of the derived class is string.
How can I tell my derived class to return the openFileDialog's FileNames and how to make the filter work? What am I missing?
