CryptographicException

A value other than Cert was passed to the contentType parameter.

-or-

The certificate could not be exported.

Remarks

The contentType parameter accepts only the Cert value of the X509ContentType enumeration. Passing any other value causes a CryptographicException to be thrown.

Security Note:
Never hard-code a password within your source code. Hard-coded passwords can be retrieved from an assembly by using the MSIL Disassembler (Ildasm.exe), by using a hexadecimal editor, or by simply opening the assembly in a text editor such as Notepad.exe.
