您需要阅读 EXIF 来自图像的数据。

您可以使用类似这样的库

  //实例化阅读器
 ExifReader阅读器=新的ExifReader（@..路径到您的图像\ ... jpg）; 

 //使用ExifTags枚举提取标记数据
 double gpsLat，gpsLng; 
 if（reader.GetTagValue< double>（ExifTags.GPSLatitude，
 out gpsLat））
 {
 //根据提取的信息做任何事情
 // ... 
} 
 if（reader.GetTagValue< double>（ExifTags.GPSLongitude，
 out gpsLng））
 {
 //做任何必需的提取的信息
 // ... 
} 
 

更新。 代码改为使用 MemoryStream

  void cam_Completed如果（e.TaskResult == TaskResult.OK）
 {
 using（MemoryStream memo = new MemoryStream（））
 {
 e.ChosenPhoto.CopyTo（备忘录）; 
 memo.Position = 0; 
 using（ExifReader reader = new ExifReader（memo））
 {
 double [] latitudeComponents; 
 reader.GetTagValue（ExifTags.GPSLatitude，out latitudeComponents）; 

 double [] longitudeComponents; 
 reader.GetTagValue（ExifTags.GPSLongitude，out longitudeComponents）; 

 // Lat / long存储为D°M'S数组，所以您需要重建它们的值，如下所示：
 var latitude = latitudeComponents [0] + latitudeComponents [1] / 60 + latitudeComponents [2] / 3600; 
 var longitude = longitudeComponents [0] + longitudeComponents [1] / 60 + longitudeComponents [2] / 3600; 

 //经度和纬度现在应该正确设置... 
} 
} 
} 
} 
 

I want to fetch the information from the image regarding the Geolocation as shown in the image below

 void cam_Completed(object sender, PhotoResult e)
        {
            if (e.TaskResult == TaskResult.OK)
            {

                Image cameraImage = new Image();
                BitmapImage bImage = new BitmapImage();

                bImage.SetSource(e.ChosenPhoto);
                cameraImage.Source = bImage;

                e.ChosenPhoto.Position = 0;

                ExifReader reader = new ExifReader(e.ChosenPhoto);
                double gpsLat, gpsLng;

                reader.GetTagValue<double>(ExifTags.GPSLatitude,
                                                    out gpsLat))

                reader.GetTagValue<double>(ExifTags.GPSLongitude,
                                                    out gpsLng))


                MessageBox.Show(gpsLat.ToString() + "" + gpsLng.ToString());   

            }
        }

so that we can detect location where the image was taken. Please help to find the these property.

You will need to read the EXIF data from the image.

You can use a library such as this

// Instantiate the reader
ExifReader reader = new ExifReader(@"..path to your image\...jpg");

// Extract the tag data using the ExifTags enumeration
double gpsLat, gpsLng;
if (reader.GetTagValue<double>(ExifTags.GPSLatitude, 
                                    out gpsLat))
{
    // Do whatever is required with the extracted information
    //...
}
if (reader.GetTagValue<double>(ExifTags.GPSLongitude, 
                                    out gpsLng))
{
    // Do whatever is required with the extracted information
    //...
}

UPDATE. Code changed to use MemoryStream

    void cam_Completed(object sender, PhotoResult e)
    {
        if (e.TaskResult == TaskResult.OK)
        {
            using (MemoryStream memo = new MemoryStream())
            {
                e.ChosenPhoto.CopyTo(memo);
                memo.Position = 0;
                using (ExifReader reader = new ExifReader(memo))
                {
                    double[] latitudeComponents;
                    reader.GetTagValue(ExifTags.GPSLatitude, out latitudeComponents);

                    double[] longitudeComponents;
                    reader.GetTagValue(ExifTags.GPSLongitude, out longitudeComponents);

                    // Lat/long are stored as D°M'S" arrays, so you will need to reconstruct their values as below:
                    var latitude = latitudeComponents[0] + latitudeComponents[1] / 60 + latitudeComponents[2] / 3600;
                    var longitude = longitudeComponents[0] + longitudeComponents[1] / 60 + longitudeComponents[2] / 3600;

                    // latitude and longitude should now be set correctly...
                }
            }
        }
    }
