通过OleDbDataAdapter将excel数据导入数据表,将方括号替换为圆形括号

标签: excel datatable square-bracket oledbdataadapter

我正在使用此代码导入excel(.xls)数据,但列中的所有方括号都被圆形替换。例如列dm [kg]:

导入前

:dm [kg]

导入后

:dm(kg)

我会感激任何帮助。

public static DataTable ImportWorkSheet(string excelFile, bool hasHeaderRow, bool allText, string tabName)

                tabName = Path.GetFileName(excelFile);
