C＃Excel VSTO：get_Range（）和Range（）之间的区别

Question

I am trying to understand the difference between Worksheet.Range() and Worksheet.get_Range(). Take the two lines of codes below:

Globals.ThisWorkbook.Worksheets["Sheet1"].Range("A4").Value2 = "test";

This will print "test" on cell A4 on worksheet labelled "Sheet1". Similarly,

Globals.ThisWorkbook.Worksheets["Sheet1"].get_Range("A4").Value2 = "test";

should produce the same result, instead I got:

'System.__ComObject' does not contain a definition for 'get_Range

Can someone explain when and how to use get_Range()?

Is there any performance benefit?

Answer 1

In C# code, a property X produces methods named get_X and set_X under the hood. Therefore, get_Range("A4") should instead be written as Range["A4"] . See the code in the first example in this MSDN document for an example.

I doubt you will see any performance difference, though as in most performance questions the answer is "try it and compare times".
