Question

我有一个excel文件存在以下问题，我希望使用下一个代码在C＃中将其各自单元格的值大写：

DbProviderFactory factory =
                    DbProviderFactories.GetFactory("System.Data.OleDb");
                DbConnection connection = factory.CreateConnection();

                string stringConnection = String.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR=NO;IMEX=1'",
                    excelPath);

                connection.ConnectionString = stringConnection;

                connection.Open();

                DbCommand updateExcel =
                    factory.CreateCommand();

                updateExcel.CommandText =
                    "UPDATE [sheet1$] SET lastname = UCASE(lastname), name = ucase(name)";

                updateExcel.Connection = connection;

                updateExcel.ExecuteNonQuery();

                conection.Close();
                connection.Dispose();

它引发了关于参数未指定的oledbexception，任何人都可以帮助我吗？

如果您尝试连接到Excel 2007或2010电子表格，则需要以下连接字符串...

OleDbConnection xlconnection = new OleDbConnection();

xlconnection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + FileName + @";Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"

使用大写文本更新excel单元格
