Answer 1

您正在使用Access Reversed符號（「$」），這是導致問題的原因。檢查此鏈接： https://support.office.com/en-us/article/Access-2007-reserved-words-and-symbols-e33eb3a9-8baa-4335-9f57-da237c63eabe?CorrelationId=05072bb5-da4f-40d0-8664-dd50ad5dbb6b&ui=en-US&rs=en-US&ad=US#__toc272229038

public DataTable GetDatas(string QueryString, string SheetName) 
     { 
      DataTable dt = new DataTable(); 
      try 
      { 
       System.Data.OleDb.OleDbConnection MyConnection; 
       System.Data.DataSet DtSet; 
       System.Data.OleDb.OleDbDataAdapter MyCommand; 
       MyConnection = new System.Data.OleDb.OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + FileName + "';Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"); 
       MyCommand = new System.Data.OleDb.OleDbDataAdapter(QueryString, MyConnection); 
       MyCommand.TableMappings.Add("Table", SheetName); 
       DtSet = new System.Data.DataSet(); 
       MyCommand.Fill(DtSet); 
       dt = DtSet.Tables[0]; 

      } 
      catch (Exception ex) 
      { 
       MessageBox.Show(ex.ToString()); 
      } 
      return dt; 
     }
