ILock.Unlock Method  IT Hit WebDAV for .NET

Removes lock with the specified token from this item or deletes lock-null item.

Parameters

lockToken

Lock with this token should be removed from the item.

Return Value

• NoContentResponse - the lock identified by the specified lock token was successfully removed from the item.
• PreconditionFailedResponse - the included lock token was not enforceable on this item.

Remarks

If this lock included more than one hierarchy item, the lock is removed from all items included in the lock. If the lock-null item is unlocked using this method then it must be removed from the WebDAV hierarchy.

Example

public WebDAVResponse Unlock(string lockToken)
{
    LockInfo[] locks = ActiveLocks;
    int i;
    
    for(i=0;i<locks.Length;i++)
        if(locks[i].Token == lockToken) break;
    
    if(i == locks.Length)
        return new PreconditionFailedResponse();

    if(this is ILockNull)
    { // delete lock-null item
        DeleteThisItem();
    }
    else
    { // remove lock from existing item
        SqlConnection conn = new SqlConnection(connStr);
        SqlCommand cmd;
        conn.Open();
        try
        {
            cmd = conn.CreateCommand();
            cmd.CommandText = "DELETE FROM Lock WHERE Token LIKE @Token";
            cmd.Parameters.Add("@Token", SqlDbType.NVarChar).Value = lockToken;
            cmd.ExecuteNonQuery();
        }
        finally
        {
            conn.Close();
        }
    }
    
    return new NoContentResponse();
