我在Visual Studio 2015中有一个Xamarin C＃项目，使我的Android应用程序使用jCIFS将文件保存到Windows共享文件夹。
这是我用来保存文件的方法：
private async Task Save2Samba(string text)
{
String sSambaFolder = "192.168.0.22/c";
String url = "smb://" + sSambaFolder + "/file.txt";
byte[] bytes = new byte[text.Length * sizeof(char)];
System.Buffer.BlockCopy(text.ToCharArray(), 0, bytes, 0, bytes.Length);
SmbFile file = null;
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, null, null);
file = new SmbFile(url, auth);
SmbFileOutputStream lol = new SmbFileOutputStream(file);
lol.Write(bytes);
lol.Flush();
lol.Close();
}
在运行时，我初始化SmbFileOutputStream的行会抛出Java.Lang.ExceptionInInitializerError并出现以下错误堆栈

我将这些权限添加到我的AndroidManifest.xml
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
