如何在 C# | IronXl.Excel 中為 Excel 單元格新增註解

This video walks through reading a CSV file into a DataTable in C# using IronXL. It covers importing the CSV data, loading it into a DataTable, and working with rows, columns, and structured datasets, all with minimal code. That makes it a good fit for reporting tools, data-migration workflows, business applications, and ETL processes that need tabular data in memory. The same approach turns a raw CSV file into a DataTable you can query and transform in any .NET application.
