...不，实际上以 google搜索开头！

您可以找到关于 Excel 和 C＃互操作性的材料，例如我们在CodeProject上有以下文章：用C＃打开和导航Excel [ ^ ]。

从 Excel ，乘法很简单（只有两次嵌套迭代）。

Hi all,
I want to multiply two matrices each matrix 3 rows and 3 columns, where one matrix is in Excel file and other matrix I have in C# Program.
How I will access to excel matrix and then multiply in C#?

Thanks All

Start here: C# Matrix Library[^] and here: http://msdn.microsoft.com/en-us/library/dd264733.aspx[^]

... no, actually start with googling!

You may find a lof of material about Excel and C# interoperability, for instance we have the following article, here at CodeProject: Opening and Navigating Excel with C#[^].
Once you have imported the matrix from Excel, the multiplication is trivial (just two nested iterations).
