在PC端获取屏幕高度，可以通过编程语言来实现。以下是一些常见编程语言中获取屏幕高度的方法：
Windows平台
1. C
```csharp
int screenHeight = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;
```
2. C++
使用Win32 API：
```cpp
int screenWidth, screenHeight;
GetSystemMetrics(SM_CYSCREEN, &screenHeight);
```
3. Python
使用`ctypes`库：
```python
from ctypes import windll
screenWidth = windll.user32.GetSystemMetrics(0)
screenHeight = windll.user32.GetSystemMetrics(1)
```
macOS平台
1. Swift
```swift
let screen = NSScreen.main!
let rect = screen.visibleFrame
let screenHeight = rect.height
```
2. Objective-C
```objective-c
NSArray screens = [NSScreen screens];
NSArray mainScreen = [screens objectAtIndex:0];
NSRect rect = [mainScreen visibleFrame];
int screenHeight = (int)rect.size.height;
```
Linux平台
1. Python
使用`Xlib`库：
```python
from Xlib import X, display
screen = display.screen()
root = screen.root
height = root.height
```
这些代码示例可以帮助你在不同的平台上获取屏幕的高度。获取屏幕尺寸时可能需要导入相应的库或模块。
