C# 在Word中添加Latex 数学公式和符号

using Spire.Doc;
 Spire.Doc.Documents;
 Spire.Doc.Fields.OMath;

namespace Create
{
    class Program
    {
        static void Main(string[] args)
        {
            //新建word实例
            Document doc = new Document();

            添加一个section
            Section section = doc.AddSection();

            添加一个段落 
            Paragraph paragraph = section.AddParagraph();

            在第一段添加公式
            OfficeMath officeMath =  OfficeMath(doc);
            paragraph.Items.Add(officeMath);
            officeMath.FromLatexMathCode("x^{2}+sqrt{x^{2}+1}=2");

            添加第二个公式到第二段
            Paragraph paragraph2 = section.AddParagraph();
            OfficeMath officeMath1 =  OfficeMath(doc);
            paragraph2.Items.Add(officeMath1);
            officeMath1.FromLatexMathCode(forall x in X,quad exists y leq epsilon添加符号到第三段 
            Paragraph paragraph3 = section.AddParagraph();
            OfficeMath officeMath2 =  OfficeMath(doc);
            paragraph3.Items.Add(officeMath2);
            officeMath2.FromLatexMathCode( alpha,beta,gamma,Gamma,pi,Pi,phi,varphi,mu,Phi保存文档       
            doc.SaveToFile(result.docx,FileFormat.Docx);
            System.Diagnostics.Process.Start();
        }
    }
