问题一
解决方法：
通常我把所有的dll复制到system32文件夹，64位系统复制到sysWOW64文件夹，而且编译选项CPU要选择X86
问题二
解决方法：
图片路径默认是C:\，对C:\没有写的权限，所以提示此错误。改变此路径到别的盘符就可以解决。
以下是我编写的代码

本人用ASP.NET开发的，图片会保存到本地，需要上传到服务器端才能在网页中查看，以下是上传图片的方法
public bool UploadPhoto(string photoPath)
{
FileStream stream = new FileStream(photoPath, FileMode.Open, FileAccess.Read);
int size = Convert.ToInt32(stream.Length);
Byte[] MeaningFile = new Byte[size];
stream.Read(MeaningFile, , size);
stream.Close();
FileStream photoStream = null; string fileName = photoPath.Substring(photoPath.LastIndexOf("\\") + );
string fileExt = photoPath.Substring(photoPath.LastIndexOf(".") + );
if (fileExt.ToLower() == "bmp")//必须是bmp文件
{
try
{
string filePath = Server.MapPath("~/IDCardPhoto/");
if (!Directory.Exists(filePath))
{
Directory.CreateDirectory(filePath);
}
if (File.Exists(Server.MapPath("~/IDCardPhoto/" + fileName)) == true) //如果存在文件
{ }
else
{
//fileName = "newFileName" + fileExt;
photoStream = new FileStream(filePath + fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite);
photoStream.Write(MeaningFile, , MeaningFile.Length);
photoStream.Close();
}
}
catch
