.NET:是什么让我的Form在Show()上调整大小

Question

在显示窗体之前，我的代码会调整其大小，但在调用其Show（）方法后，它的大小既不是初始化时的大小。。。Designer.vb，也不是我刚刚设置的。

我在它的Resize（）处理程序中设置了一个断点，从Show（）到Resize（

我假设有一些组件的位置和大小会迫使Form根据自己的需求进行调整，但我真的无法从堆栈跟踪中判断出来，也不知道如何找出原因。

有什么建议吗？

TIA

您的AutoScaleMode设置为默认值Font，并且您指定了一个比Windows默认值更大（或更小）的字体。

我怀疑表单的初始大小很小，这将导致您看到的行为。如果是，请给表单一个等于初始大小的MinimumSize（而不是0,0）。如果您还没有提供最小大小，那么在调用GetClientRect（）和GetWindowRect（（）时（在调用UpdateBounds（）期间），它似乎是根据您的环境为您计算的。对我来说，这是113x28。
