如果要读取文本文件内容并将其转换为DataTable，那么您的文件内容应为xml类型或应为json序列化字符串。首先，将文件内容修改为json或xml格式，然后尝试将其转换为datatable ..为此，您可以使用

 json.pa RSE（YourFileTextString）; 

I have a text file whose content is like below


---------------------Start file-----------------------------------------------------------------
[BEGIN STATEMENT BATCH]
A1 data.............................
H1 data.............................

If you want to read your text file contents and convert it to DataTable, then your file content should be of xml type or should be json serialized string.. First, modify your file contents to json or xml format, and then try converting it to datatable.. For that, you can use

json.parse(YourFileTextString);
