##### Syntax

    public sealed class VerificationResult : IDisposable

### Methods

#### Dispose()

##### Declaration

    public override sealed void Dispose()

#### Dispose(bool)

##### Declaration

    [HandleProcessCorruptedStateExceptions]
    protected void Dispose(bool A_0)

##### Parameters

Type | Name | Description
--- | --- | ---
bool | A_0 |

#### ~VerificationResult()

##### Declaration

    protected ~VerificationResult()

#### GetDigestAlgorithm()

Retrieves an enumeration value representing the digest algorithm used to sign the signature that is associated with this verification result. For DocTimeStamp signatures, returns the weakest algorithm found (between the CMS and message imprint digests).

##### Declaration

    public DigestAlgorithm.Type GetDigestAlgorithm()

##### Returns

Type | Description
--- | ---
DigestAlgorithm.Type | A DigestAlgorithm enumeration value

#### GetDigestStatus()

Retrieves the digest-related result condition associated with a digital signature verification operation.

##### Declaration

    public VerificationResult.DigestStatus GetDigestStatus()

##### Returns

Type | Description
--- | ---
VerificationResult.DigestStatus | A DigestStatus-type enumeration value

#### GetDigestStatusAsString()

Retrieves the digest-related result condition associated with a digital signature verification operation, as a descriptive string.

##### Declaration

    public string GetDigestStatusAsString()

##### Returns

Type | Description
--- | ---
string | a string

#### GetDigitalSignatureField()

Retrieves the digital signature field associated with the digital signature verification operation that returned this result.

##### Declaration

    public DigitalSignatureField GetDigitalSignatureField()

##### Returns

Type | Description
--- | ---
DigitalSignatureField | A DigitalSignatureField object

#### GetDisallowedChanges()

Retrieves a list of informational structures regarding any disallowed changes that have been made to the document since the signature associated with this verification result was signed.

##### Declaration

    public DisallowedChange[] GetDisallowedChanges()

##### Returns

Type | Description
--- | ---
DisallowedChange[] | a collection of DisallowedChange objects.

#### GetDocumentStatus()

Retrieves the document-related result condition associated with a digital signature verification operation.

##### Declaration

    public VerificationResult.DocumentStatus GetDocumentStatus()

##### Returns

Type | Description
--- | ---
VerificationResult.DocumentStatus | A DocumentStatus-type enumeration value

#### GetDocumentStatusAsString()

Retrieves the document-related result condition associated with a digital signature verification operation, as a descriptive string.

##### Declaration

    public string GetDocumentStatusAsString()

##### Returns

Type | Description
--- | ---
string | a string

#### GetPermissionsStatus()

Retrieves the result condition about permissions checks performed on any unsigned modifications associated with a digital signature verification operation.

##### Declaration

    public VerificationResult.ModificationPermissionsStatus GetPermissionsStatus()

##### Returns

Type | Description
--- | ---
VerificationResult.ModificationPermissionsStatus | A ModificationPermissionsStatus-type enumeration value

#### GetPermissionsStatusAsString()

Retrieves the result condition about permissions checks performed on any unsigned modifications associated with a digital signature verification operation, as a descriptive string.

##### Declaration

    public string GetPermissionsStatusAsString()

##### Returns

Type | Description
--- | ---
string | a string

#### GetTrustStatus()

Retrieves the trust-related result condition associated with a digital signature verification operation.

##### Declaration

    public VerificationResult.TrustStatus GetTrustStatus()

##### Returns

Type | Description
--- | ---
VerificationResult.TrustStatus | A TrustStatus-type enumeration value

#### GetTrustStatusAsString()

Retrieves the trust-related result condition associated with a digital signature verification operation, as a descriptive string.

##### Declaration

    public string GetTrustStatusAsString()

##### Returns

Type | Description
--- | ---
string | a string

#### GetTrustVerificationResult()

Retrieves the detailed result associated with the trust step of the verification operation that returned this VerificationResult, if such a detailed trust result is available. Must call HasTrustVerificationResult first and check for a true result.

##### Declaration

    public TrustVerificationResult GetTrustVerificationResult()

##### Returns

Type | Description
--- | ---
TrustVerificationResult | An optional TrustVerificationResult

#### GetUnsupportedFeatures()

Retrieves reports about unsupported features encountered during verification. This function is the canonical source of information about all unsupported features encountered. Current possible values: "Document Security Store" (includes VRI, which is part of DSS dictionary), "unsupported signature encoding", "usage rights signature", "legal content attestations", "unsupported digest algorithm"

##### Declaration

    public string[] GetUnsupportedFeatures()

##### Returns

Type | Description
--- | ---
string[] | a container of strings representing unsupported features encountered during verification

##### Remarks

Output may change in future versions.

#### GetVerificationStatus()

Retrieves the main verification status. The main status is determined based on the other statuses. Verification may fail for many reasons; some of these reasons are the presence of features that are not supported yet. It may be desirable for you to report unsupported signatures differently (for example, using a question mark rather than an X mark). Any unsupported features encountered can be retrieved by the use of the function GetUnsupportedFeatures on this class.

##### Declaration

    public bool GetVerificationStatus()

##### Returns

Type | Description
--- | ---
bool | A boolean representing whether or not the verification operation was completely successful

#### HasTrustVerificationResult()

Returns whether there is a detailed TrustVerificationResult in this VerificationResult or not.

##### Declaration

    public bool HasTrustVerificationResult()

##### Returns

Type | Description
--- | ---
bool | A boolean.
