我已经接管了使用SQLite数据库并在与WebService相同的PC上完美本地运行的UWP应用程序。我使用商店在Microsoft Surface(x64 Windows 10 Professional
)上运行它们来创建软件包。
应用程序通过PC的IP在PC上的ASP.Net中调用SOAP WebService-x64 Windows 10 Professional
-(处于开发阶段,因此不在服务器上)。该API从SQL Server数据库创建一个SQLite数据库,然后以另一种方法将其返回。
这是我的问题:
在创建到SQLite数据库的连接时(我从与WebService处于同一台PC上的.db文件中,使用SqliteConnectionStringBuilder
获得了connectionString),发生了错误:
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
因此,我在不同的论坛上进行了搜索并测试了不同的解决方案(在x86 / x64 / ARM / Any CPU中生成UWP应用程序,在x86 / x64 / Any CPU中生成API),但没有任何效果。所以我真的不知道该怎么办。你有什么想法吗?
代码:
/// <summary>
/// Creates the SQLite database from the schema read from the SQL Server.
/// </summary>
/// <param name="sqlitePath">The path to the generated DB file.</param>
/// <param name="schema">The schema of the SQL server database.</param>
/// <param name="password">The password to use for encrypting the DB or null if non is needed.</param>
private static void CreateSQLiteDatabase(string sqlitePath, DatabaseSchema schema, string password,bool createViews)
{
// Create the SQLite database file
SQLiteConnection.CreateFile(sqlitePath);
// Connect to the newly created database
string sqliteConnString = CreateSQLiteConnectionString(sqlitePath, password);
//Here the exception
using (SQLiteConnection conn = new SQLiteConnection(sqliteConnString))
{
conn.Open();
...
CreateSQLiteConnectionString方法:
/// <summary>
/// Creates SQLite connection string from the specified DB file path.
/// </summary>
/// <param name="sqlitePath">The path to the SQLite database file.</param>
/// <returns>SQLite connection string</returns>
private static string CreateSQLiteConnectionString(string sqlitePath, string password)
{
SQLiteConnectionStringBuilder builder = new SQLiteConnectionStringBuilder();
builder.DataSource = sqlitePath;
if (password != null)
builder.Password = password;
builder.PageSize = 4096;
builder.UseUTF16Encoding = false;
string connstring = builder.ConnectionString;
return connstring;
}
我不知道是否缺少dll,这是我第一次使用UWP和SQLite。
预先感谢您的回答。

有了StackOverflow的问题建议,我找到了答案:
我必须在IIS的应用程序池中允许32位应用程序。 (I get a "An attempt was made to load a program with an incorrect format" error on a SQL Server replication project)
