在SQLite官方下載了System.Data.SQLite,編寫如下測試代碼:
復制內容到剪貼板 程序代碼
using (SQLiteConnection conn = new SQLiteConnection(@"Data Source=F:\my.db;Pooling=true;FailIfMissing=false"))
{
using (SQLiteDataAdapter adapter = new SQLiteDataAdapter("select id,total from table1", conn))
{
DataTable table1 = new DataTable();
adapter.Fill(table1);
MessageBox.Show(table1.Rows[0]["total"].ToString());
}
}
{
using (SQLiteDataAdapter adapter = new SQLiteDataAdapter("select id,total from table1", conn))
{
DataTable table1 = new DataTable();
adapter.Fill(table1);
MessageBox.Show(table1.Rows[0]["total"].ToString());
}
}
運行出錯,在new SQLiteConnection處提示:

無法加載 DLL“SQLite.Interop.dll”: 找不到指定的模塊。 (異常來自 HRESULT:0x8007007E)。
解決方法
我下載的System.Data.SQLite版本是Precompiled Binaries for 32-bit Windows (.NET Framework 3.5 SP1),這個版本提供了兩個zip包:
①.sqlite-netFx35-binary-bundle-Win32-2008-1.0.79.0.zip
引用內容
This binary package features the mixed-mode assembly and contains all the binaries for the x86 version of the System.Data.SQLite 1.0.79.0 (3.7.10) package. The Visual C++ 2008 SP1 runtime for x86 and the .NET Framework 3.5 SP1 are required.
②.sqlite-netFx35-binary-Win32-2008-1.0.79.0.zip
引用內容
This binary package contains all the binaries for the x86 version of the System.Data.SQLite 1.0.79.0 (3.7.10) package. The Visual C++ 2008 SP1 runtime for x86 and the .NET Framework 3.5 SP1 are required.
我在項目引用的是第②個zip中的System.Data.SQLite.dll,運行出錯,改為引用第①個zip中的System.Data.SQLite.dll即可正常運行。
