When manipulating excel cells in C# (via an COM object), should I use the .Value or .Value2 ? that is
在C#中操作excel单元格时(通过COM对象),我应该使用.Value还是.Value2?那是
sheet.Cells[row + n, col].Value = "Hello world"
or
sheet.Cells[row + n, col].Value2 = "Hello world"
What is the difference between them to ?
他们之间有什么区别?
Also, how do I set a cell format to "General" ?
另外,如何将单元格格式设置为“常规”?
sheet.Cells[row + n, col].NumberFormat = "XYZ"; // Not sure what should be here
Right now when I assign a cell with the number "0,34" and even if I do
现在当我指定一个数字为“0,34”的单元格时,即使我这样做了
sheet.Cells[row + n, col].NumberFormat = "@";
I get this "little error" sign up in the left corner in each cell
我在每个单元格的左角收到这个“小错误”注册

To answer the first question you should read this article: http://blogs.msdn.com/b/eric_carter/archive/2004/09/06/225989.aspx

The optional parameters part doesn't apply anymore since C# 4.0 has optional parameters.
可选参数部分不再适用,因为C#4.0具有可选参数。
But there IS a difference (stated in the article)
但是有一点不同(在文章中说明)
The only difference between this property [Value2] and the Value property is that the Value2 property doesn’t use the Currency and Date data types. You can return values formatted with these data types as floating-point numbers by using the Double data type.
此属性[Value2]和Value属性之间的唯一区别是Value2属性不使用Currency和Date数据类型。您可以使用Double数据类型将使用这些数据类型格式化的值作为浮点数返回。
For the second question, have you tried setting a cell to 'General' and reading it out in code?
对于第二个问题,您是否尝试将单元格设置为“常规”并在代码中读取它?
I think it's sheet.Cells[row + n, col].NumberFormat = "General", where "@" is pure text.
我认为它是sheet.Cells [row + n,col] .NumberFormat =“General”,其中“@”是纯文本。

In order to get the General type, as "magic string" that should to be assigned to the NumberFormat property try to use the empty string, e.g.
为了获得General类型,作为应该分配给NumberFormat属性的“magic string”,尝试使用空字符串,例如
sheet.Cells[5, 7].NumberFormat = ""; // sets the cell type to the General type
