Wix 布尔属性值不起作用
我有以下属性：
<Property Id="UPDATEDB">1</Property>
UI 中绑定到该属性的复选框：
<Control Id="updateDatabase" Type="CheckBox" CheckBoxValue="1" Height="15" Width="95" X="20" Y="74" Text="Update Database" Property="UPDATEDB" />
以及一个自定义操作，它根据此属性的值执行某些操作
<CustomAction Id="RunDbMigration" Directory="INSTALLDIR" Return="check"
ExeCommand='[DBMIGRATIONDIR]\DbMigration.exe' />
<InstallExecuteSequence>
<Custom Action="RunDbMigration" After="InstallFinalize">UPDATEDB=1 AND NOT Installed</Custom>
</InstallExecuteSequence>
如果我尝试从命令行传递 UPDATEDB 的值 0：
msiexec /i "Setup.msi" /l* UPDATEDB=0
或
msiexec /i "Setup.msi" /l* UPDATEDB="0"
值无论如何，该复选框都会被选中。也就是说，传入的 0 似乎受到尊重，并且 RunDbMigration 操作未运行...
这里发生了什么？为什么这是如此复杂的科学？
I have the following property:
<Property Id="UPDATEDB">1</Property>
A checkbox in the UI bound to that property:
<Control Id="updateDatabase" Type="CheckBox" CheckBoxValue="1" Height="15" Width="95" X="20" Y="74" Text="Update Database" Property="UPDATEDB" />
And a Custom Action which does something based on the value of this property
<CustomAction Id="RunDbMigration" Directory="INSTALLDIR" Return="check"
ExeCommand='[DBMIGRATIONDIR]\DbMigration.exe' />
<InstallExecuteSequence>
<Custom Action="RunDbMigration" After="InstallFinalize">UPDATEDB=1 AND NOT Installed</Custom>
</InstallExecuteSequence>
If I try to pass a value of 0 for UPDATEDB from the command line:
msiexec /i "Setup.msi" /l* UPDATEDB=0
or
msiexec /i "Setup.msi" /l* UPDATEDB="0"
the value of the checkbox is checked anyway. That said, the 0 passed in seems to be respected and the RunDbMigration action is not run...
What's going on here? Why is this such rocket science?

正如其他人提到的，复选框不是 1/0 意义上的布尔值，而是 null/not-null 意义上的布尔值。
要从命令行取消设置 - 您可能需要使用类似的内容
，您的条件可能在执行自定义操作之前专门查找 1 的值，这就是您的 CA 未运行的原因。
As others have mentioned, Checkboxes are not boolean in a 1/0 sense, they're boolean in a null/not-null sense.
To unset from the command line - you would want to use something like
Chances are that your condition is looking specifically for the value of 1 before executing your custom action, which is why your CA isn't being run.
安装程序属性要么设置为一个值，要么不设置。在内部，该值只是一个字符串，因此“0”、“1”、“true”和“false”是相同的。
当复选框控件的属性设置为某个值（无关紧要）时，复选框控件将被选中；而当其属性为空时，复选框控件将被取消选中。
此命令行设置属性并选中复选框：
此命令行不设置属性，因此未选中复选框：
Installer properties are either set to a value or they are not set. Internally the value is just a string, so "0", "1", "true" and "false" are the same.
A checkbox control is checked when its property is set to a value (doesn't matter what) and unchecked when its property is empty.
This command line sets the property and checks the checkbox:
This command line doesn't set the property, so the checkbox is not checked:
