首先要添加引用com组件：

然后引用：

using Word = Microsoft.Office.Interop.Word;

/// <summary>
        /// 读取 word文档返回内容
        /// </summary>
        /// <param name="path"></param>
        /// <returns></returns>
        public static string GetWordContent(string path)
        {
            try
            {
                Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
                Type wordType = app.GetType();
                Microsoft.Office.Interop.Word.Document doc = null;
                object unknow = Type.Missing;
                app.Visible = false;

                object file = path;
                doc = app.Documents.Open(ref file,
                ref unknow, ref unknow, ref unknow, ref unknow,
                ref unknow, ref unknow, ref unknow, ref unknow,
                ref unknow, ref unknow, ref unknow, ref unknow,
                ref unknow, ref unknow, ref unknow);
                int count = doc.Paragraphs.Count;
                StringBuilder sb = new StringBuilder();
                for (int i = 1; i <= count; i++)
                {

                    sb.Append(doc.Paragraphs[i].Range.Text.Trim());
                }

                doc.Close(ref unknow, ref unknow, ref unknow);
                wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, app, null);
                doc = null;
                app = null;
                //垃圾回收
                GC.Collect();
                GC.WaitForPendingFinalizers();

                string temp = sb.ToString();
                //if (temp.Length > 200)
                // return temp.Substring(0, 200);
                //else
                return temp;
            }
            catch
            {
                return "";
            }
        }
