Delete Method

Delete()

Deletes the signature.

Use this method to remove the current signature from its parent ISignatureSet. For a visible signature line, deleting the signature removes that signature entry from the workbook. In digital signature only mode, this method can be used to remove the digital signature from a signed signature line or to remove a non-visible signature.

Declaration

void Delete()

Sub Delete()

Examples

ISignature signature = workbook.Signatures.AddSignatureLine(worksheet, 100.0, 50.0);
signature.Setup.SuggestedSigner = "Kenji Tenzai";
signature.Delete();

Exceptions

Type	Condition
InvalidOperationException	Thrown if the workbook is opened in digital signature only mode and the current signature is an unsigned visible signature line.
