想将pdf中的"中国银行" 替换成 “美国银行” 怎么做到

You need to find the fragment to be replaced using TextFragmentAbsorber and execute
absorber.TextFragments[0].Text=“new text”

抱歉 没太明白 这是我的代码 我应该怎么写呢
public class Test {

public static final Set<String> set = new HashSet();

public static void main(String[] args) {
    // Open document
    Document pdfDocument = new Document("D:\\word_test\\copy_pdf_test.pdf");

    replace(pdfDocument,"中国银行","美国银行");

    pdfDocument.save("D:\\word_test\\qq.pdf");

}

public static void replace( Document pdfDocument,String source,String target){
    TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber(source);

    // Accept the absorber for all pages of document
    pdfDocument.getPages().accept(textFragmentAbsorber);
    // Get the extracted text fragments into collection
    TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();

    // Loop through the fragments
    for (TextFragment textFragment :  textFragmentCollection) {
        textFragment.getRectangle();
        textFragment.setInLineParagraph(true);
        Position baselinePosition = textFragment.getBaselinePosition();
        double xIndent = baselinePosition.getXIndent();
        double yIndent = baselinePosition.getYIndent();
        if(!set.contains(baselinePosition.getXIndent() + "-" + baselinePosition.getYIndent())){
            set.add(xIndent + "-" + yIndent);
            // Update text and other properties
            textFragment.setText(target);
        }
    }
}

}

in C# it looks like this

public static void replace(Document pdfDocument, string source, string target)
{
    var textFragmentAbsorber = new TextFragmentAbsorber(source);
    textFragmentAbsorber.TextReplaceOptions.ReplaceAdjustmentAction = TextReplaceOptions.ReplaceAdjustment.WholeWordsHyphenation;
    pdfDocument.Pages[1].Accept(textFragmentAbsorber);

    textFragmentAbsorber.TextFragments[1].Text = target;
}
