我在让 Winforms (C#) 自动缩放正常工作时遇到了重大问题。

首先，它似乎甚至没有跨 DPI 做任何事情。当我创建一个简单的应用程序时，所有控件在 100% 和 125% DPI 下都显示相同的大小，但是我所有控件中的字体都在 125% DPI 下放大了。我希望表单会被放大以允许更大的字体，但事实并非如此。这可能是因为该应用程序不是“DPI-Aware”，因此它使用 XP Style 字体缩放，但我不太确定。这是它的外观：

以 100% DPI 应用，未本地化：

以 100% DPI 应用，未本地化

以 125% DPI 应用，未本地化：

以 125% DPI 应用，未本地化

上述问题令人沮丧，但不破坏交易。不幸的是，还有另一个问题。当我的简单表单将其“Localizable”属性设置为 true 时（因此所有控件的大小和位置都存储在resx文件中）：

Visual Studio 可本地化选项

... RichTextBox 控件变得太高了：

以 125% DPI 应用，本地化：

以 125% DPI 应用，本地化

不幸的是，我正在处理的应用程序是一个非常古老的应用程序。它在 Winforms 中设计了超过 500 个控件/对话框，因此不可能迁移到 WPF。

所以，我的问题基本上是这样的：为什么简单地将控制位置放在resx文件中会破坏 125% DPI 的布局？我怎样才能解决这个问题？

Form1.resx

<?xml version="1.0" encoding="utf-8"?>
<root>
  <!-- 
    Microsoft ResX Schema 

    Version 2.0

    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.

    Example:

    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>

    There are any number of "resheader" rows that contain simple 
    name/value pairs.

    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.

    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:

    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.

    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

我在缩放问题上经历了很多次战斗。我将分享我的处理方法。

首先，有一种“作弊”方式：在所有 UserControl 和 Windows 上，将属性“AutoScaleMode”设置为“None”。我称之为作弊，因为我相信它基本上忽略了缩放并将其保持在 100%，最终用户可能不会欣赏。

其次，我发现处理它的最佳方法是使用“TableLayoutPanel”。我发现一旦我熟悉了 TableLayoutPanel，我就能让控件变得更快、更清晰、可调整大小和可缩放。

诀窍是永远不要设置固定宽度。固定宽度将固定单元格大小，当控件缩放时，它将超出该单元格大小。对于诸如标签之类的控件（一旦出现在屏幕上，它将始终是一个设定的大小），将行/列设置为 autozie。对于富文本框等控件，将其设置为 %。如果您需要在侧面留有空白，请创建一个空行/列并给它一个 % 值。

最后，因为所有这些都是 % 值，所以当它们变得太小时，事情会看起来很糟糕。为了让用户能够使用您的应用程序，无论他们的窗口大小是多少，在设计器中将其缩小到您希望控件的最小大小，然后将“AutoScrollMinSize”设置为该大小。当控件小于您设置的值时，这将显示滚动条。

我希望这有助于您处理缩放！
