所以我正在研究这个东西，它将一个excel指令列表转换成一个更好看的、格式化的word文档。我一直在连接到 excel 文档，然后将文件存储到数据表中以便于访问。
当我开始遇到错误时，我终于为我的 word 文档找到了正确的边框和内容：
External table is not in the expected format.
这是完整的连接算法：
public static DataTable getWorkSheet(string excelFile =
"C:\\Users\\Mitch\\Dropbox\\Work tools\\Excel for andrew\\Air Compressor PM's.xlsx") {
string connection = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + excelFile
+ ";Extended Properties='Excel 8.0;HDR=YES;'";
string sql = null;
string worksheetName = null;
string[] Headers = new string[4];
DataTable schema = null;
DataTable worksheet = null;
DataSet workbook = new DataSet();
//Preparing and opening connection
OleDbConnection objconn = new OleDbConnection(connection);
objconn.Open();
//getting the schema data table
schema = objconn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
worksheetName = schema.Rows[0]["Table_Name"].ToString();
//Each worksheet will have a varying name, so the name is just called from
//the dataTable.rows array. Can be later modified to use multiple
//worksheets within a workbook.
sql = "SELECT * FROM[" + worksheetName + "]";
//data adapter
OleDbDataAdapter objAdapter = new OleDbDataAdapter();
//pass the sql
objAdapter.SelectCommand = new OleDbCommand(sql, objconn);
//populate the dataset
objAdapter.Fill(workbook);
//Remove spaces from the headers.
worksheet = workbook.Tables[0];
for (int x = 0; x < Headers.Count(); x++) {
Headers[x] = worksheet.Columns[x].ColumnName;
worksheet.Columns[x].ColumnName = worksheet.Columns[x].ColumnName.Replace(" ", "");
}
return worksheet;
}//end of getWorksheet
编辑：我从 dropbox 以前的版本中提取了我的旧代码，这些版本确实可以正常工作，并重新下载了我知道正在工作的 excel 文档的副本.....什么给了？我的电脑有什么变化吗？
