Answer 1

Replace:

string connStr = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=xxx;Extended Properties=""Excel 12.0 Xml;HDR=YES""");

with

string connStr = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=YES""", newFileName);

如果您仍然收到如下错误“Microsoft Access 数据库引擎找不到对象...”，后跟您尝试从中读取数据的工作表名称，然后尝试 [工作表名称 $]。
