推荐答案

您需要传递全名.

全名是My.Namespaces.MyForm

You need to pass the full name.
http://msdn.microsoft.com/en-us/library/dex1ss7c.aspx[^]

The full name would be My.Namespaces.MyForm

在我看来，您在设计时具有Form的类型.您可以使用其他方法通过反射来创建表单，例如 Activator.GetInstance(Of frmMyForm) [ ^ ].
另请注意，实例化Form的最佳方法是仅调用构造函数.
像这样:

It seems to me that you have the type of the Form at designtime. You could use other methods to create your Form using reflection, like Activator.GetInstance(Of frmMyForm)[^].
Also note that the best way to instantiate a Form is by simply calling the constructor.
Like so:

frmMyForm frm = New frmMyForm();
frm.Show();
