c# code to add new attribute value to a block

[Anonymous]

I wanted to add new attribute value to block by opening a autocad drawing & selecting block for which the new attribute value should be added

Thank you for the Code,
Unfortunately the inserted attribute does not appear in the block editor.

What could be the problem?

As said in replies #6 and #8, the attribute is added to some block reference, not to the block definition (which is what you see in the block editor).
