Excel's Range object (C #)

Original: Excel's Range object (C #)

The Range object is the most frequently used object in an Excel application, and you need to represent it as a Range object before you manipulate any area within Excel, and then use the methods and properties of the Range object. A Range object represents a cell, a row, a column, a selected cell that contains one or more cell blocks (which can be contiguous cells, or a non-contiguous cell), or even a group of cells on multiple worksheets. References a range in code. Address Property: This property returns a string of range coordinates, expressed in one of several formats, including: "$A $1"(cell in position A1)," "$1"(on the first row of the worksheet) and" $A $1: $C $5(the range includes all the cells in the rectangle between A1 and C5). "$" represents absolute coordinates (not relative coordinates).
