使用 C# 在項目中插入現有數據庫文件

Question

我正在開發一個應用程序，它獲取用戶的公共 IP 地址，在數據庫中查找該 IP 地址的位置，獲取緯度和經度，最后顯示該地點的日出和日落時間。

為了使第二步工作，我需要在我的項目中實現一個數據庫文件。 我已經下載了數據庫文件（.bin - 格式），但我無法將我的程序與下載的數據庫文件連接起來。

下載數據庫文件如下：

我該如何解決這個問題？

干杯!

您可以使用 IP2Location NuGet 包https://www.nuget.org/packages/IP2Location.IPGeolocation/並像下面這樣調用它：

Dim oIPResult As New IP2Location.IPResult
Dim oIP2Location As New IP2Location.Component
Try
    Dim strIPAddress = "8.8.8.8"
    If strIPAddress.Trim <> "" Then
        oIP2Location.Open("C:\myfolder\IP-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE-ZIPCODE-TIMEZONE-ISP-DOMAIN-NETSPEED-AREACODE-WEATHER-MOBILE-ELEVATION-USAGETYPE-ADDRESSTYPE-CATEGORY.BIN", True)
        oIPResult = oIP2Location.IPQuery(strIPAddress)
        Select Case oIPResult.Status
            Case "OK"
                Console.WriteLine("IP Address: " & oIPResult.IPAddress)
                Console.WriteLine("City: " & oIPResult.City)
                Console.WriteLine("Country Code: " & oIPResult.CountryShort)
                Console.WriteLine("Country Name: " & oIPResult.CountryLong)
                Console.WriteLine("Postal Code: " & oIPResult.ZipCode)
                Console.WriteLine("Domain Name: " & oIPResult.DomainName)
                Console.WriteLine("ISP Name: " & oIPResult.InternetServiceProvider)
                Console.WriteLine("Latitude: " & oIPResult.Latitude)
                Console.WriteLine("Longitude: " & oIPResult.Longitude)
                Console.WriteLine("Region: " & oIPResult.Region)
                Console.WriteLine("TimeZone: " & oIPResult.TimeZone)
                Console.WriteLine("NetSpeed: " & oIPResult.NetSpeed)
                Console.WriteLine("IDD Code: " & oIPResult.IDDCode)
                Console.WriteLine("Area Code: " & oIPResult.AreaCode)
                Console.WriteLine("Weather Station Code: " & oIPResult.WeatherStationCode)
                Console.WriteLine("Weather Station Name: " & oIPResult.WeatherStationName)
                Console.WriteLine("MCC: " & oIPResult.MCC)
                Console.WriteLine("MNC: " & oIPResult.MNC)
                Console.WriteLine("Mobile Brand: " & oIPResult.MobileBrand)
                Console.WriteLine("Elevation: " & oIPResult.Elevation)
                Console.WriteLine("Usage Type: " & oIPResult.UsageType)
                Console.WriteLine("Address Type: " & oIPResult.AddressType)
                Console.WriteLine("Category: " & oIPResult.Category)
            Case "EMPTY_IP_ADDRESS"
                Console.WriteLine("IP Address cannot be blank.")
            Case "INVALID_IP_ADDRESS"
                Console.WriteLine("Invalid IP Address.")
            Case "MISSING_FILE"
                Console.WriteLine("Invalid Database Path.")
        End Select
    Else
        Console.WriteLine("IP Address cannot be blank.")
    End If
Catch ex As Exception
    Console.WriteLine(ex.Message)
Finally
    oIP2Location.Close()
    oIPResult = Nothing
    oIP2Location = Nothing
End Try
