 借助Spire.Doc，我們可以很方便的在word文檔中添加超鏈接和編輯超鏈接。本文將重點(diǎn)演示如何在 C# 中刪除 word 文檔中的所有超鏈接。

下面就詳細(xì)介紹如何去除word文檔中的超鏈接。首先，查看帶有許多超鏈接的示例文檔：

第 1 步：創(chuàng)建一個新的 word 文檔并從文件中加載示例文檔：

Document doc = new Document();
doc.LoadFromFile("Sample.docx");

第 2 步：創(chuàng)建一個方法 FindAllHyperlinks() 以獲取示例文檔中的所有超鏈接。

private List FindAllHyperlinks(Document document)
{
List hyperlinks = new List();
foreach (Section section in document.Sections)
{
foreach (DocumentObject sec in section.Body.ChildObjects)
{
if (sec.DocumentObjectType == DocumentObjectType.Paragraph)
{
foreach (DocumentObject para in (sec as Paragraph).ChildObjects)
{
if (para.DocumentObjectType == DocumentObjectType.Field)
{
Field field = para as Field;

if (field.Type == FieldType.FieldHyperlink)
{
hyperlinks.Add(field);
}
}
}
}
}
}
return hyperlinks;
}

第 3 步：刪除超鏈接的字體顏色和下劃線格式。

private void FormatFieldResultText(Body ownerBody,int sepOwnerParaIndex,int endOwnerParaIndex,int sepIndex,int endIndex)
{
for (int i = sepOwnerParaIndex; i <= endOwnerParaIndex; i++)
{
Paragraph para = ownerBody.ChildObjects[i] as Paragraph;
if (i == sepOwnerParaIndex && i == endOwnerParaIndex)
{
for (int j = sepIndex + 1; j < endIndex; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}

}
else if (i == sepOwnerParaIndex)
{
for (int j = sepIndex + 1; j < para .ChildObjects .Count ; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
else if (i == endOwnerParaIndex)
{
for (int j = 0; j < endIndex; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
else
{
for (int j = 0; j < para.ChildObjects.Count; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
}
}
private void FormatText(TextRange tr)
{
tr.CharacterFormat.TextColor = Color.Black;
tr.CharacterFormat.UnderlineStyle = UnderlineStyle.None;
}

第 4 步：展平超鏈接字段。

private void FlattenHyperlinks(Field field)
{
int ownerParaIndex = field.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.OwnerParagraph);
int fieldIndex = field.OwnerParagraph.ChildObjects.IndexOf(field);
Paragraph sepOwnerPara = field.Separator.OwnerParagraph;
int sepOwnerParaIndex = field.Separator.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.Separator.OwnerParagraph);
int sepIndex = field.Separator.OwnerParagraph.ChildObjects.IndexOf(field.Separator);
int endIndex = field.End.OwnerParagraph.ChildObjects.IndexOf(field.End);
int endOwnerParaIndex = field.End.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.End.OwnerParagraph);

FormatFieldResultText(field.Separator.OwnerParagraph.OwnerTextBody, sepOwnerParaIndex, endOwnerParaIndex, sepIndex, endIndex);

field.End.OwnerParagraph.ChildObjects.RemoveAt(endIndex);

for (int i = sepOwnerParaIndex; i >= ownerParaIndex; i--)
{
if (i == sepOwnerParaIndex && i == ownerParaIndex)
{
for (int j = sepIndex; j >= fieldIndex; j--)
{
field.OwnerParagraph.ChildObjects.RemoveAt(j);

}
}
else if (i == ownerParaIndex)
{
for (int j = field.OwnerParagraph.ChildObjects.Count - 1; j >= fieldIndex; j--)
{
field.OwnerParagraph.ChildObjects.RemoveAt(j);
}

}
else if (i == sepOwnerParaIndex)
{
for (int j = sepIndex; j >= 0; j--)
{
sepOwnerPara.ChildObjects.RemoveAt(j);
}
}
else
{
field.OwnerParagraph.OwnerTextBody.ChildObjects.RemoveAt(i);
}
}
}

第 5 步：將文檔保存到文件

doc.SaveToFile("removehyperlinks.docx", FileFormat.Docx);

去除word文檔超鏈接后的有效截圖：

如何從word文檔中刪除超鏈接的完整代碼：

public Removehyperlink()
{
Document doc = new Document();
doc.LoadFromFile("Sample.docx");

List hyperlinks = FindAllHyperlinks(doc);

for (int i = hyperlinks.Count - 1; i >= 0; i--)
{
FlattenHyperlinks(hyperlinks[i]);
}

doc.SaveToFile("removehyperlinks.docx", FileFormat.Docx);

}
private List FindAllHyperlinks(Document document)
{
List hyperlinks = new List();
foreach (Section section in document.Sections)
{
foreach (DocumentObject sec in section.Body.ChildObjects)
{
if (sec.DocumentObjectType == DocumentObjectType.Paragraph)
{
foreach (DocumentObject para in (sec as Paragraph).ChildObjects)
{
if (para.DocumentObjectType == DocumentObjectType.Field)
{
Field field = para as Field;

if (field.Type == FieldType.FieldHyperlink)
{
hyperlinks.Add(field);
}
}
}
}
}
}
return hyperlinks;
}

private void FlattenHyperlinks(Field field)
{
int ownerParaIndex = field.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.OwnerParagraph);
int fieldIndex = field.OwnerParagraph.ChildObjects.IndexOf(field);
Paragraph sepOwnerPara = field.Separator.OwnerParagraph;
int sepOwnerParaIndex = field.Separator.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.Separator.OwnerParagraph);
int sepIndex = field.Separator.OwnerParagraph.ChildObjects.IndexOf(field.Separator);
int endIndex = field.End.OwnerParagraph.ChildObjects.IndexOf(field.End);
int endOwnerParaIndex = field.End.OwnerParagraph.OwnerTextBody.ChildObjects.IndexOf(field.End.OwnerParagraph);

FormatFieldResultText(field.Separator.OwnerParagraph.OwnerTextBody, sepOwnerParaIndex, endOwnerParaIndex, sepIndex, endIndex);

field.End.OwnerParagraph.ChildObjects.RemoveAt(endIndex);

for (int i = sepOwnerParaIndex; i >= ownerParaIndex; i--)
{
if (i == sepOwnerParaIndex && i == ownerParaIndex)
{
for (int j = sepIndex; j >= fieldIndex; j--)
{
field.OwnerParagraph.ChildObjects.RemoveAt(j);

}
}
else if (i == ownerParaIndex)
{
for (int j = field.OwnerParagraph.ChildObjects.Count - 1; j >= fieldIndex; j--)
{
field.OwnerParagraph.ChildObjects.RemoveAt(j);
}

}
else if (i == sepOwnerParaIndex)
{
for (int j = sepIndex; j >= 0; j--)
{
sepOwnerPara.ChildObjects.RemoveAt(j);
}
}
else
{
field.OwnerParagraph.OwnerTextBody.ChildObjects.RemoveAt(i);
}
}
}

private void FormatFieldResultText(Body ownerBody, int sepOwnerParaIndex, int endOwnerParaIndex, int sepIndex, int endIndex)
{
for (int i = sepOwnerParaIndex; i <= endOwnerParaIndex; i++)
{
Paragraph para = ownerBody.ChildObjects[i] as Paragraph;
if (i == sepOwnerParaIndex && i == endOwnerParaIndex)
{
for (int j = sepIndex + 1; j < endIndex; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}

}
else if (i == sepOwnerParaIndex)
{
for (int j = sepIndex + 1; j < para.ChildObjects.Count; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
else if (i == endOwnerParaIndex)
{
for (int j = 0; j < endIndex; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
else
{
for (int j = 0; j < para.ChildObjects.Count; j++)
{
FormatText(para.ChildObjects[j] as TextRange);
}
}
}
}
private void FormatText(TextRange tr)
{
tr.CharacterFormat.TextColor = Color.Black;
tr.CharacterFormat.UnderlineStyle = UnderlineStyle.None;
}
