SQLite3.dll問題x64

Question

我用一個簡單的解決方法解決了我的問題SQLite sqlite3_column_origin_name function，但現在我又遇到了另一個大問題。

我已經與這些進口sqlwrapper：

[DllImport("sqlite3.dll", EntryPoint = "sqlite3_column_int")] 
    static extern int sqlite3_column_int(IntPtr stmHandle, int iCol); 

    [DllImport("sqlite3.dll", EntryPoint = "sqlite3_column_text")] 
    static extern string sqlite3_column_text(IntPtr stmHandle, int iCol); 

    [DllImport("sqlite3.dll", EntryPoint = "sqlite3_column_double")] 
    static extern double sqlite3_column_double(IntPtr stmHandle, int iCol); 

，這是我的executeQuery功能：

public DataTable ExecuteQuery(String query) 
    { 

     SQLiteWrapper.query = query; 

     if (!_open) 
      throw new SQLiteException("SQLite database is not open."); 

     //prepare the statement 
     IntPtr stmHandle = IntPtr.Zero; 
     try 
     { 
      stmHandle = Prepare(query); 
     } 
     catch(Exception e) 
     { 
      Log.e(e.Message); 
      return null; 
     } 


     // Prevensione sul out of memory 
     if(stmHandle == IntPtr.Zero) 
     { 
      return null; 
     } 

     //get the number of returned columns 
     int columnCount = sqlite3_column_count(stmHandle); 

     DataTable dTable = null; 
     try 
     { 
      //create datatable and columns 
      dTable = new DataTable(); 
      for (int i = 0; i < columnCount; i++) 
      { 
       try 
       { 
        ArrayList selections = Utils.getQuerySelection(query); 
        foreach(String s in selections) 
        { 
         dTable.Columns.Add(s); 
        } 
        //Workaround for sqlite3_column_origin_name 

        //dTable.Columns.Add("_id"); 
        //dTable.Columns.Add(sqlite3_column_origin_name(stmHandle, i)); 
       } 
       catch(Exception e) 
       { 

       } 
      } 

      //populate datatable 
      while (sqlite3_step(stmHandle) == SQLITE_ROW) 
      { 
       object[] row = new object[columnCount]; 
       for (int i = 0; i < columnCount; i++) 
       { 
        switch (sqlite3_column_type(stmHandle, i)) 
        { 

         case SQLITE_INTEGER: 
          // WORKS CORRECTLY!!!! 
          row[i] = sqlite3_column_int(stmHandle, i); 
          break; 
         case SQLITE_TEXT: 
          // ERROR!!!!!!!!!!!!!!!!!!!!!! 
          row[i] = sqlite3_column_text(stmHandle, i); 
          break; 
         case SQLITE_FLOAT: 
          row[i] = sqlite3_column_double(stmHandle, i); 
          break; 
        } 
       } 
       dTable.Rows.Add(row); 
      } 
     } 
     catch(AccessViolationException ave) 
     { 
      Log.e("SqliteWrapper - AccessViolationException - " + ave.Message + ":" + query); 
      return null; 
     } 

     // Se ci sono stati errori allora torna null e ritenta la query 
     Boolean finalized = Finalize(stmHandle); 
     if(!finalized) 
     { 
      return null; 
     } 
     return dTable; 
    } 

當我調用sqlite3_column_text（......）我的應用程序崩潰。 我已經探索了dll文件中的函數，並且存在這個入口點「sqlite3_column_text」。

我可以解決我的問題嗎？

編輯：我從http://sourceforge.net/projects/sqlite-dotnet2/files/SQLite%20for%20ADO.NET%202.0/1.0.66.0/

試試下面的代碼

[DllImport("sqlite3.dll", EntryPoint = "sqlite3_column_text")] 
    static extern string sqlite3_column_text(IntPtr stmHandle, int iCol); 

串→IntPtr的

[DllImport("sqlite3.dll", EntryPoint = "sqlite3_column_text")] 
static extern IntPtr sqlite3_column_origin_name(IntPtr stmHandle, int iCol); 

row[i] = Marshal.PtrToStringAnsi(sqlite3_column_text(stmHandle, i));
