我正在尝试使用 OLEDB 替换 Excel 2007 中的表格。

首先，我正在执行命令“Drop Table”，而不是“Create Table”，它工作正常。

但是如果我现在想将数据插入("INSERT INTO")到这个表中，它就会失败。没有错误或异常OleDbCommand.ExecuteNonQuery()，事务最终成功提交，数据库只是空的。

任何想法为什么？

connection.Open();
string access_com = "DROP TABLE " + globalPrefix + prefix + TableName;
OleDbCommand execute = new OleDbCommand(access_com, connection);
try
{
  execute.ExecuteNonQuery();
}
catch (Exception ex)
{
  ConfigDataSet.Log.AddLogRow("The program cannot drop table you want. Close the file with it and run program again!", 1);
  return 1;
}
access_com = "CREATE TABLE [" + globalPrefix + prefix + TableName + "]" + fieldString + ")";// CONSTRAINT PK" + TableName + " PRIMARY KEY " + primaryKey + ")";
execute.CommandText = access_com;
execute.ExecuteNonQuery();

OleDbTransaction transaction = connection.BeginTransaction();
access_com = "INSERT INTO " + TableName + "( " + allfields + ")" + " VALUES (" + parametersString + ")";
OleDbCommand execute = new OleDbCommand(access_com, connection);
execute.Transaction = transaction;
try
{
  execute.ExecuteNonQuery();
  execute.Parameters.Clear();
}
catch (OleDbException ex)
{
  ConfigDataSet.Log.AddLogRow("Inserting row failed: ", 2);
  failedInsertions++;
}

您在事务中有 INSERT 查询，但我在您的代码中的任何地方都看不到提交：

execute.ExecuteNonQuery();
transaction.Commit();

您可能还应该transaction.Rollback();在您的异常块中有。请参见OleDbConnection.BeginTransaction 方法
