Был затронут после обновления Mac до High Sierra, это успешно разрешило его для меня:
brew unlink python
xcode-select --install
brew install python
I looked at my own code and can see that I access the properties using late binding. I can't remember why, but I'll post some code in case it helps.
object properties = workBk.GetType().InvokeMember("CustomDocumentProperties", BindingFlags.Default | BindingFlags.GetProperty, null, workBk, null);
object property = properties.GetType().InvokeMember("Item", BindingFlags.Default | BindingFlags.GetProperty, null, properties, new object[] { propertyIndex });
object propertyValue = property.GetType().InvokeMember("Value", BindingFlags.Default | BindingFlags.GetProperty, null, propertyWrapper.Object, null);
EDIT: ah, now I remember why. :-)
EDIT 2: Jimbojones' answer - to use the dynamic keyword - is a better solution (if you value ease-of-use over the performance overhead of using dynamic
).
Я нашел решение здесь .
Вот код, который у меня получился:
public void SetDocumentProperty(string propertyName, string propertyValue)
{
object oDocCustomProps = workBk.CustomDocumentProperties;
Type typeDocCustomProps = oDocCustomProps.GetType();
object[] oArgs = {propertyName,false,
MsoDocProperties.msoPropertyTypeString,
propertyValue};
typeDocCustomProps.InvokeMember("Add", BindingFlags.Default |
BindingFlags.InvokeMethod, null,
oDocCustomProps, oArgs);
}
private object GetDocumentProperty(string propertyName, MsoDocProperties type)
{
object returnVal = null;
object oDocCustomProps = workBk.CustomDocumentProperties;
Type typeDocCustomProps = oDocCustomProps.GetType();
object returned = typeDocCustomProps.InvokeMember("Item",
BindingFlags.Default |
BindingFlags.GetProperty, null,
oDocCustomProps, new object[] { propertyName });
Type typeDocAuthorProp = returned.GetType();
returnVal = typeDocAuthorProp.InvokeMember("Value",
BindingFlags.Default |
BindingFlags.GetProperty,
null, returned,
new object[] { }).ToString();
return returnVal;
}
Некоторая обработка исключений необходима, если свойство не существует, когда получено
