C# 在 OpenFileDialog 中不显示过滤器扩展

发布于 2024-12-25 18:45:33 字数 220 浏览 0 评论 0原文

我在 OpenFileDialog 的 Filter 属性中有多个扩展。是否可以隐藏扩展名并仅显示描述？

示例：

dialog.Filter = "Image files|*.bmp;*.jpg; many image file extensions here"

我只想在文件类型组合框中显示文本：“图像文件”，因为扩展字符串很长。这可能吗？

I have multiple extensions in the Filter property of OpenFileDialog. Is possible to hide the extensions and show only the description?

Sample:

dialog.Filter = "Image files|*.bmp;*.jpg; many image file extensions here"

I want to show only the text: "Image files" in the file type combo box because the extension string is very long. Is this possible?

这

dialog.Filter = "Image files (*.bmp)|*.bmp;*.jpg"

将仅在组合框中显示“图像文件 (*.bmp)”，同时仍显示具有所有指定扩展名的文件。

或者您可以

dialog.Filter = "Image files (*.bmp;...)|*.bmp;*.jpg"

指示它查找扩展名为 bmp 和其他一些扩展名的文件。

这可能取决于操作系统。我用 Windows 7 进行了测试。

This

dialog.Filter = "Image files (*.bmp)|*.bmp;*.jpg"

will only display "Image files (*.bmp)" in the combo box while still showing files with all the specified extensions.

Or you could do

dialog.Filter = "Image files (*.bmp;...)|*.bmp;*.jpg"

to indicate that it looks for files with extension bmp and some other extensions.

This might depend on the OS. I tested with Windows 7.

这应该有效：

    dialog.Filter = "All Supported Audio | *.mp3; *.wma | MP3s | *.mp3 | WMAs | *.wma";
    dialog.AutoUpgradeEnabled = false; //using FileDialog.AutoUpgradeEnabled = false it will display the old XP sytle dialog box, which then displays correctly
    dialog.ShowDialog();

This should work:

    dialog.Filter = "All Supported Audio | *.mp3; *.wma | MP3s | *.mp3 | WMAs | *.wma";
    dialog.AutoUpgradeEnabled = false; //using FileDialog.AutoUpgradeEnabled = false it will display the old XP sytle dialog box, which then displays correctly
    dialog.ShowDialog();

它应该完全按照您在问题中所写的那样工作：

dialog.Filter = "Image files|*.bmp;*.jpeg;*.jpg;*.png;*.gif"

It should work exactly as you wrote in your question:

dialog.Filter = "Image files|*.bmp;*.jpeg;*.jpg;*.png;*.gif"

这很简单，你知道。请参阅以下代码片段。它将完美运行。您可以像这样定义更多文件类型。

OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "JPG Files(*.jpg)|*.jpg|PNG Files(*.png)|*.png|BMP Files(*.bmp)|*.bmp|GIF Files(*.gif)|*.gif|TIFF Files(*.tiff)|*.tiff|All Files(*.*)|*.*";

Filter 属性中有两个部分。 "JPG Files(.jpg)|.jpg" 表示选择文件类型的下拉列表将显示 "JPG Files(*.jpg)" 并且过滤器将针对管道字符的下一部分即 *.jpg。

注意： 切勿在 *.jpg 后使用任何空格或任何其他文件类型。如果使用，它无法过滤您想要的文件类型。

。

It is very simple, you know. See the following code snippet. It will run perfectly. You can define more file-types like this way.

OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "JPG Files(*.jpg)|*.jpg|PNG Files(*.png)|*.png|BMP Files(*.bmp)|*.bmp|GIF Files(*.gif)|*.gif|TIFF Files(*.tiff)|*.tiff|All Files(*.*)|*.*";

There are two parts in the Filter property. "JPG Files(.jpg)|.jpg" means the dropdown for selecting file-types will show "JPG Files(*.jpg)" and the filter will happen against the next part of pipe character i.e. *.jpg.

Note: Never use any space after *.jpg or be it any other file-type. If used, it cannot filter your desired file-type.
