我正在使用FileHelpers库将csv文件导入数据库表.我在导入文件时遇到问题,该文件的字段以文件头中的数字('800NUMBER')开头.

导入代码:
DataTable data = CommonEngine.CsvToDataTable(file, ',');

例外:
FileHelpers.FileHelpersException: The string '800NUMBER' not is a valid .NET identifier. at FileHelpers.RunTime.FieldBuilder..ctor(String fieldName, String fieldType) at FileHelpers.RunTime.DelimitedClassBuilder.AddField(String fieldName, String fieldType) at FileHelpers.RunTime.CsvClassBuilder.AddField(String fieldName, String fieldType) at FileHelpers.RunTime.DelimitedClassBuilder.AddField(String fieldName) at FileHelpers.RunTime.CsvClassBuilder..ctor(CsvOptions options) at FileHelpers.CsvEngine.CsvToDataTable(String filename, String classname, Char delimiter, Boolean hasHeader) at FileHelpers.CommonEngine.CsvToDataTable(String filename, Char delimiter)

我不确定是否有办法逃脱列名称,如'[800NUMBER]'.

列名称无法更改,因为这是客户端向我们提供的方式.

通过分别从'data'行读取'header'行解决了这个问题.然后,我更改'data'中的列名并使用SqlBulkCopy导入数据库.

    FileHelpers.CsvOptions options = new FileHelpers.CsvOptions("ImportRecord", ',', file);
    options.HeaderLines = 0;        

    FileHelpers.CsvEngine engine = new FileHelpers.CsvEngine(options);

    engine.Options.IgnoreFirstLines = 0; 
    DataTable header = engine.ReadStringAsDT(FileHelpers.CommonEngine.RawReadFirstLines(file, …
