C#中npoi或者其他方法导出word文档完整前后台代码

我想用C#做个简历导出的类似功能，但是导出word格式时存在问题，请大神指教，最好有完整前后台代码 最好简单点

XWPFParagraph p0 = doc.CreateParagraph();
p0.SetAlignment(ParagraphAlignment.LEFT);
XWPFRun r0 = p0.CreateRun();
r0.SetFontFamily("宋体");
r0.SetFontSize(18);
r0.SetBold(true);
r0.SetText("未登录过学生的账号密码");

        XWPFParagraph p1 = doc.CreateParagraph();
        p1.SetAlignment(ParagraphAlignment.LEFT);
        XWPFRun r1 = p1.CreateRun();
        r1.SetFontFamily("宋体");
        r1.SetFontSize(10);
        r1.SetBold(true);
        r1.SetText("(备注：已登录过的学生密码不显示)");

        XWPFParagraph p2 = doc.CreateParagraph();
        p2.SetAlignment(ParagraphAlignment.LEFT);
        XWPFRun r2 = p2.CreateRun();
        r2.SetFontFamily("宋体");
        r2.SetFontSize(10);
        r2.SetBold(true);
        r2.SetText("学校：XX一中");

        XWPFParagraph p3 = doc.CreateParagraph();
        p3.SetAlignment(ParagraphAlignment.LEFT);
        XWPFRun r3 = p3.CreateRun();
        r3.SetFontFamily("宋体");
        r3.SetFontSize(10);
        r3.SetBold(true);
        r3.SetText("班级：(7)");

        XWPFParagraph p4 = doc.CreateParagraph();
        p4.SetAlignment(ParagraphAlignment.LEFT);
        XWPFRun r4 = p4.CreateRun();
        r4.SetFontFamily("宋体");
        r4.SetFontSize(10);
        r4.SetBold(true);
        r4.SetText("班主任：ddd");


        XWPFParagraph p5 = doc.CreateParagraph();
        p5.SetAlignment(ParagraphAlignment.LEFT);
        XWPFRun r5 = p5.CreateRun();
        r5.SetFontFamily("宋体");
        r5.SetFontSize(10);
        r5.SetBold(true);
        r5.SetText("可以在此处添加备注：");

doc.Write(new FifleStream("文件名"))
