我必须从服务器检索到Android手机的所有尺寸的图像参考编号，让我试着用下面这样的编码，并成功拿到了基地64串和base64string它工作于小尺寸的图像检索到的图像等效的，但是当我去对于大尺寸图片仍然黑屏无法通过这种方法来获得屏幕的大尺寸图像。

提前致谢。

如何检索

通过肥皂对象大尺寸的base64串从服务器

                pname.setText("");


            }

        this.ext.setOnClickListener(new View.OnClickListener() {

                System.exit(0);
            }
        });





    }
}

它返回null soapprimitive（结果），当它返回的图像尺寸大于150KB或2500 * 3000渔政船

[WebMethod]
    public string  IMAGE(string ID)
    {

SqlConnection conn = new SqlConnection("Data Source=;Initial Catalog=;Persist Security Info=True;User ID=sa;");
        conn.Open();
        SqlDataAdapter sdImageSource = new SqlDataAdapter();
        sdImageSource.SelectCommand = new SqlCommand("select ImageData from ImagesStore where ImageId=('" + ID + "')", conn);
        DataSet dsImage = new DataSet();
        sdImageSource.Fill(dsImage);
        byte[] blob = (byte[])dsImage.Tables[0].Rows[0][0];
        int k = blob.Length;
        string c = Convert.ToBase64String(blob);
        return c;
}

这是我的建议的Base64编码的图像存储在服务器的文件夹，并保存在数据库中的路径，所以你可以很容易地检索
