asp.net实现word文档在线查看功能 （三种方法）

1.通过javascript打开＼编辑＼根据模板新建word文档

//"SharePoint.OpenDocuments.1"可与Office XP兼容

var openDocObj = new ActiveXObject("SharePoint.OpenDocuments.2");

//打开文档

openDocObj.ViewDocument(lUrl+"./documents/sample.doc");

//ViewDocument()方法还有一个重载签名，可以让我们手工指定激活哪个程序来打开文档：

openDocObj.ViewDocument(lUrl+"./documents/sample.doc", 要激活的程序的ProgID);

//编辑文档

var lUrl = window.location.href;

openDocObj.EditDocument(lUrl+"./documents/sample.doc");

//根据模板创建文档(模板,新文档保存路径)

openDocObj.CreateNewDocument(lUrl+"./documents/sampleTemplate.dot", lUrl+"./documents/");

注：iis必须设置为可写，web服务扩展中的WebDaV应是允许状态

２．直接把文件上传进数据库

string FileName;

Stream WordStream = SearchFile.PostedFile.InputStream;

string FilePath = this.SearchFile.PostedFile.FileName;

FileName = Path.GetFileName(FilePath);

if (FileName != null && FileName != "")

{

int WordLen = SearchFile.PostedFile.ContentLength;

string WordType = SearchFile.PostedFile.ContentType;

byte[] WordData = new Byte[WordLen];

int n = WordStream.Read(WordData, 0, WordLen);

WordStream.Close();

SqlCommand com = new SqlCommand();

com.CommandText = "insert into MyTable(name,FileBinary) values(@FileName,@FileBinary)";

com.Parameters.Add(new System.Data.SqlClient.SqlParameter("@FileName", System.Data.SqlDbType.Char, 20, "FileName"));

com.Parameters.Add(new System.Data.SqlClient.SqlParameter("@FileBinary", System.Data.SqlDbType.Image, WordData.Length, "FileBinary"));

com.Connection = sqlConnection;

com.Parameters["@FileName"].Value = FileName;

com.Parameters["@FileBinary"].Value = WordData;

com.Connection.Open();

com.ExecuteNonQuery();

com.Connection.Close();

}

else

{

Response.Write(" ");

}

３．数据流的方式在浏览器中显示Word文件

Response.ContentType = "Application/msword";

this.Response.Clear();

SqlCommand selcom = new SqlCommand();

selcom.CommandText = "select name,FileBinary from MyTable order by id desc";

selcom.Connection = sqlConnection;

selcom.Connection.Open();

SqlDataReader dr = selcom.ExecuteReader();

dr.Read();

Byte[] b = new Byte[(dr.GetBytes(1, 0, null, 0, int.MaxValue))];

dr.GetBytes(1, 0, b, 0, b.Length);

dr.Close();

selcom.Connection.Close();

System.IO.Stream fs = this.Response.OutputStream;

fs.Write(b, 0, b.Length);

fs.Close();

this.Response.End();
