Question

我已经使用nuget将WriteableBitmapEx下载到我的WP7项目

我可以看到它在我项目的references文件夹中添加了两个引用

我似乎无法找到将依赖项添加到我的类中的方法。这是班级：

namespace Microsoft.Samples.CRUDSqlAzure.Phone.Converters
{
using System;
using System.Windows.Data;
using System.IO;
using System.Windows.Media.Imaging;
using System.Windows;



public class ImageByteConverter : IValueConverter
{
    /// <summary>
    /// Converts a Jpeg byte array into a WriteableBitmap
    /// </summary>
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null)
            return null;

        byte[] val = (byte[])value;

        MemoryStream ms = new MemoryStream(val);
        return WriteableBitmapExtentions.DecodeJpeg(ms);
    }
    /// <summary>
    /// Converts a WriteableBitmap into a Jpeg byte array.
    /// </summary>
    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null)
            return null;
        WriteableBitmap wb = (WriteableBitmap)value;
        return wb.EncodeJpeg();
    }
}
}

WritableBitmapEx与WritableBitmapExtensions不同！

请检查here以获取WritableBitmapExtensions的代码！

使用WritableBitmapEx时缺少依赖性
