Attempts to read an Integer value from source with a specified tag under the specified encoding rules as a signed 32-bit value.

- source
- ReadOnlySpan<Byte>
The buffer containing encoded data.
- ruleSet
- AsnEncodingRules
The encoding constraints to use when interpreting the data.
- value
- Int32
On success, receives the interpreted numeric value. This parameter is treated as uninitialized.
- bytesConsumed
- Int32
When this method returns, the total number of bytes for the encoded value. This parameter is treated as uninitialized.
The tag to check for before reading, or null for the default tag (Universal 2).
Returns
true if the Integer represents value is between Int32.MinValue and Int32.MaxValue, inclusive; otherwise, false.
Exceptions
ruleSet is not defined.
The next value does not have the correct tag.
-or-
The length encoding is not valid under the current encoding rules.
-or-
The contents are not valid under the current encoding rules.
