Question

我的代码

var appView = Windows.UI.ViewManagement.ApplicationView.getForCurrentView();
appView.titleBar.backgroundColor = Windows.UI.Colors.black; // or {a: 255, r: 0, g: 0, b: 0}
appView.titleBar.inactiveBackgroundColor = Windows.UI.Colors.black;
appView.titleBar.buttonBackgroundColor = Windows.UI.Colors.black;
appView.titleBar.buttonHoverBackgroundColor = Windows.UI.Colors.black;
appView.titleBar.buttonPressedBackgroundColor = Windows.UI.Colors.black;
appView.titleBar.buttonInactiveBackgroundColor = Windows.UI.Colors.black;

获取构建错误！为什么我不能用字符串值名称创建子文件夹并插入图像？仍然无法作为名称userid插入到该crated文件夹。

Answer 1

是的，你可以。但您必须首先创建该文件夹，然后保存位图：

string folderName = @"C:\temper\temp\"+userid;
if (!Directory.Exists(folderName) {
    Directory.CreateDirectory(folderName);
}
bitmap.save(folderName + "\\userimage.jpg");  //your original concatenation had an error

Answer 2

解决！

string folderName = @"C:\temper\temp\"+userid;
if (!Directory.Exists(folderName) {
Directory.CreateDirectory(folderName);
}
bitmap.save(folderName + "\\" +userimage+ ".jpg"); `Create first folder and save Thanks Mnieto`

带有字符串值的bitmap.save子文件夹
