有没有办法从C编译的库中使用和调用方法调用,如PJSIP库？
我想使用和调用我编译的pjsip lib中的调用,但显而易见的问题是pjsip是一个C库而不是一个java库,即一个jar文件.
可能？也许是JNI？
谢谢
编辑:尝试使用Swig来完成手头的任务,但它只是创建一个空的类文件.
这是我用来执行swig的命令:
swig -verbose -java -package com.josh.sip.util -o jni_wrapper.c pjsua.i
swig命令输出

我希望能够在没有安装单词的情况下将docx文件转换为文件pdf.那里可能有免费的图书馆吗？我真的不想为此付出代价.我读了一篇文章XSL-FO,我发现了一个XSL-FOpdf转换库,不知道是否有效.
所以没有使用Microsoft.Office.Interop.Word我想转换docx为pdf
项目概况
我有一个视图绑定到包含2 ObserverableCollection的viewmodel.viewmodel构造函数填充第一个ObserverableCollection,并收集视图datacontext以通过名为Sites的公共属性绑定到它.
稍后,在LoadOrders方法中填充2ed ObserverableCollection,并更新公共属性LoadFraudResults以将其与datacontext绑定.
我正在使用WCF从数据库中提取数据并将其拉得非常好.
VIEWMODEL来源
class ManageFraudOrderViewModel:ViewModelBase
{
#region Fields
private readonly ICollectionView collectionViewSites;
private readonly ICollectionView collectionView;
private ObservableCollection<GeneralAdminService.Website> _sites;
private ObservableCollection<FraudService.OrderQueue> _LoadFraudResults;

#region Properties
public ObservableCollection<GeneralAdminService.Website> Sites
{
get { return this._sites; }
}
public ObservableCollection<FraudService.OrderQueue> LoadFraudResults
{

GeneralAdminService.Website[] websites = generalAdminServiceClient.GetWebsites();

我希望在复制文本时,它也会复制单词之间的确切空格.
在我的新课程中,我将此代码放在顶部:

private static readonly Random RandomGen = new Random();
private List<string> _words;
private List<string> _scrambledWords;
public ScrambleTextBoxText(List<string> textBoxList)
{
_words = textBoxList;
}
然后在底部我有这个功能:
public List<string> scrambledTextBoxWords()
{
List<string> words = _scrambledWords;
return words;
}
然后在按钮点击事件的Form1中我有:
private void BtnScrambleText_Click(object sender, EventArgs e)
{
textBox1.Enabled = false;
BtnScrambleText.Enabled = false;
textBoxWords = ExtractWords(textBox1.Text);
ScrambleTextBoxText scrmbltb = new ScrambleTextBoxText(textBoxWords);
