不使用C#.net返回表单名称
问题描述：
//formname包含值("EditFrom")
//但以下returnFromName显示为空
returnFromName =(FormClas)Assembly.GetEntryAssembly().CreateInstance(formname);
//formname contains the value ("EditFrom")
//but the following returnFromName shows null
returnFromName=(FormClas)Assembly.GetEntryAssembly().CreateInstance(formname);
答
您需要传递全名.

全名是My.Namespaces.MyForm
You need to pass the full name.

The full name would beMy.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();
