From here on out, only the code has a double meaning. Enclosing the Name
Logic code also come out good

This. Of the 78 line is the design document Name="Form1", because it has already been appointed a this. The Name is a list of attributes,

I want to ask, is this a bug, of course, can not use the name data source properties is ok, but the problem is very strange

CodePudding user response:

Tip is correct, change the idea to look at problems, encountered before, it is ok to remove,

CodePudding user response:

What's the strange, your name covers the definition of the original name, equivalent to two name
You define a variable type 2, how can not complain
