在我的适用于Windows 8.1(商店)和Windows Phone 8.1的通用应用程序中,仅在Store App中打开数据库时出现异常。代码是为两者共享的,对于Windows Phone,它正在运行。
class MemoDB
{
public static SQLiteConnection conn;
public MemoDB() {
conn = LoadDatabase();
}
static private SQLiteConnection LoadDatabase()
{
// Get a reference to the SQLite database
conn = new SQLiteConnection("ct_history.sqlite");
...
}
}
异常{"无法设置临时目录。"}出现在最后显示的代码行中,详情如下:
SQLitePCL.SQLiteException was not handled by user code.

InnerException:
在我看来," DLL sqlite3.dll:无法找到指定的模块"指着这个问题。我已经检查了路径" C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v8.1 \ ExtensionSDKs \ SQLite.WinRT81 \ 3.8.5 \"并在所有配置中发现DLL(ARM,x64,x86)。
正确设置SQLite for Windows运行时(Windows 8.1)(版本3.8.5.0)和SQLitePCL(v4.0.30319)的引用。
知道该怎么做?
答案 0 :(得分:5)
即使我已经好几次,我也再次删除了Windows Runtime(Windows 8.1)的参考。但这次我还删除了适用于Windows的Microsoft Visual C ++ 2013 Runtime Package的参考。在我再次添加之后,问题就消失了。
