if Recordsis your DataTabledo this:
如果Records你DataTable这样做：
Records.Rows[i][j] = value;
this does not answer the whole question but shows you how to set a value in a DataTable "cell".
这并没有回答整个问题，而是向您展示了如何在数据表“单元格”中设置一个值。
you are using the ItemArraywhich is not needed because once you have the right Row you can simply access its columns withh []
您正在使用ItemArray不需要的，因为一旦您拥有正确的行，您就可以简单地访问其列[]
you can elaborate more and find out the final solution based on this hint.
您可以详细说明并根据此提示找出最终解决方案。

If you use Records.Rows[0].ItemArray[2] = valuethis won't work, but if you use Records.Rows[0][2] = valuethis works perfectly.
如果你使用Records.Rows[0].ItemArray[2] = value它不会工作，但如果你使用Records.Rows[0][2] = value它完美。
