使用OleDb插入Excel多次覆盖错误的行

Question

我正在尝试使用OleDbConnection插入现有的Excel电子表格。我注意到，当我插入时，即使我指定了工作表偏移量，它仍然写入错误的行。更糟糕的是，每条记录都被写入同一行！这是我的代码：

static void Main(string[] args)
{
    string destination = @"C:\publish\output.xlsx";
    File.Copy(@"C:\publish\template.xlsx", destination, true);
    string connectionString = getConnectionString(destination);
    using (OleDbConnection connection = new OleDbConnection(connectionString))
    {
        connection.Open();

        using (OleDbCommand command = connection.CreateCommand())
        {
            command.CommandText = @"
INSERT INTO [Advertisers$A3:AC] 
VALUES
(
?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?
)";
            // Spit out 29 bogus values
            for (int i = 0; i != 29; ++i)
            {
                addParameter(command, "Value = " + i);
            }

            // Insert 1200 records
            for (int i = 0; i != 1200; ++i)
            {
                command.ExecuteNonQuery();
            }
        }
    }
}

private static string getConnectionString(string path)
{
    OleDbConnectionStringBuilder builder = new OleDbConnectionStringBuilder();
    builder.Provider = "Microsoft.ACE.OLEDB.12.0";
    builder.Add("Extended Properties", "Excel 12.0 Xml");
    builder.DataSource = path;
    return builder.ConnectionString;
}

private static void addParameter(OleDbCommand command, object value)
{
    OleDbParameter parameter = command.CreateParameter();
    parameter.ParameterName = "?";
    parameter.Value = value == null ? DBNull.Value : value;
    command.Parameters.Add(parameter);
}

我基本上将相同的代码复制到不同的控制台应用程序，它按预期工作。嗯？在比较两个项目一段时间之后，我注意到在项目属性下，在Build下，选中了Prefer 32-bit复选框。取消选中它解决了我的问题！
