c#/vb.net 删除 word 中的空白行-ag凯发旗舰厅

本文将介绍通过使用控件spire.doc for .net来删除word文档中多余的空白行，使文档排版更为紧凑、美观。

测试文档：

//实例化document类的对象
document doc = new document();
//加载测试文档
doc.loadfromfile("test.docx");
//遍历文档，判定段落中是否包含空白行，删除空白行
foreach (section section in doc.sections)
{
    for (int i = 0; i < section.body.childobjects.count; i  )
    {
        if (section.body.childobjects[i].documentobjecttype == documentobjecttype.paragraph)
        {
            if (string.isnullorempty((section.body.childobjects[i] as paragraph).text.trim()))
            {
                section.body.childobjects.remove(section.body.childobjects[i]);
                i--;
            }
        }
    }
}
//保存文档
string result = "result.docx";
doc.savetofile(result, fileformat.docx2013);

'实例化document类的对象
dim doc as document = new document
'加载测试文档
doc.loadfromfile("test.docx")
'遍历文档，判定段落中是否包含空白行，删除空白行
for each section as section in doc.sections
    dim i as integer = 0
    do while (i < section.body.childobjects.count)
        if (section.body.childobjects(i).documentobjecttype = documentobjecttype.paragraph) then
            if string.isnullorempty(ctype(section.body.childobjects(i),paragraph).text.trim) then
                section.body.childobjects.remove(section.body.childobjects(i))
                i = (i - 1)
            end if
            
        end if
        
        i = (i   1)
    loop
    
next
'保存文档
dim result as string = "result.docx"
doc.savetofile(result, fileformat.docx2013)
