推荐答案

我猜测您的默认构造函数中有某些设计人员无法处理的内容.

创建您的应用程序调用的重载构造函数，或者将现有构造函数中的有害代码放入如果在设计器中打开了表单则不执行的块中.

It''s my guess that you have something in the default constructor that the designer can''t cope with.

Create an overloaded constructor that your application calls, or put the offending code in the existing constructor into a block that that doesn''t execute if the form is opened in the designer.

public sub New()
    InitializeComponents()
    if (not this.DesignMode) then
        '' your code goes here
    endif
end sub
