C#实现对Word文件读写

　　手头上的一个项目报表相对比较简单，所以报表打印采用VBA引擎，通过定制Word模版，然后根据模版需要填充数据，然后OK,打印即可。

　　实现方法：首先需要引用VBA组建,我用的是Office2003 Professional，Dll版本号为Microsoft Word11.0

　　另外当然还需要引用Interop.Word.Dll.

　　代码如下：

///#region 打开Word文档,并且返回对象wDoc,wDoc
///
/// 打开Word文档,并且返回对象wDoc,wDoc
///
/// 完整Word文件路径+名称
/// 返回的Word.Document wDoc对象
/// 返回的Word.Application对象
public static void CreateWordDocument(string FileName,ref Word.Document wDoc,ref Word.Application WApp)
{
if(FileName == "") return;
Word.Document thisDocument = null;
Word.FormFields formFields = null;
Word.Application thisApplication = new Word.ApplicationClass();
thisApplication.Visible = true;
thisApplication.Caption = "";
thisApplication.Options.CheckSpellingAsYouType = false;
thisApplication.Options.CheckGrammarAsYouType = false;

Object filename = FileName;
Object ConfirmConversions = false;
Object ReadOnly = true;
Object AddToRecentFiles = false;

Object PasswordDocument = System.Type.Missing;
Object PasswordTemplate = System.Type.Missing;
Object Revert = System.Type.Missing;
Object WritePasswordDocument = System.Type.Missing;
Object WritePasswordTemplate = System.Type.Missing;
Object Format = System.Type.Missing;
Object Encoding = System.Type.Missing;
Object Visible = System.Type.Missing;
Object OpenAndRepair = System.Type.Missing;
Object DocumentDirection = System.Type.Missing;
Object NoEncodingDialog = System.Type.Missing;
Object XMLTransform = System.Type.Missing;

try
{
Word.Document wordDoc =
thisApplication.Documents.Open(ref filename, ref ConfirmConversions,
ref ReadOnly, ref AddToRecentFiles, ref PasswordDocument, ref PasswordTemplate,
ref Revert,ref WritePasswordDocument, ref WritePasswordTemplate, ref Format,
ref Encoding, ref Visible, ref OpenAndRepair, ref DocumentDirection,
ref NoEncodingDialog, ref XMLTransform );

thisDocument = wordDoc;
wDoc = wordDoc;
WApp = thisApplication;
formFields = wordDoc.FormFields;
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}

}
#endregion

　调用上面静态方法，打开目标文件并且把DataGrid中数据填充到对应Word标签中去
///#region Word填充数据(For Example)
///
/// Word填充数据
///
private void WordLoadData()
{
Word.Document wDoc=null;
Word.Application wApp=null;
sysFun.CreateWordDocument("E:\\监测报告(new).dot",ref wDoc,ref wApp);

//对标签"C"进行填充
object bkmC="C";
if(wApp.ActiveDocument.Bookmarks.Exists("C") == true)
{
wApp.ActiveDocument.Bookmarks.get_Item
(ref bkmC).Select();
}
wApp.Selection.TypeText(this.txt1.Text);
object bkmG = "TWaterTable3";
object unit;
object count; //移动数
object extend;

extend = Word.WdMovementType.wdExtend;
unit = Word.WdUnits.wdCell;
//把DataGrid中数据填充到标签TWaterTable3上
if(wApp.ActiveDocument.Bookmarks.Exists("TWaterTable3") == true)
{
wApp.ActiveDocument.Bookmarks.get_Item
(ref bkmG).Select();

for(int i=0;i {
if(i==0)
{
count=1;
}
else
{
count=0;
}
//需填充5列数据
wApp.Selection.Move(ref unit,ref count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[0].Text);
count=1;

wApp.Selection.Move(ref unit,ref count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[1].Text);

wApp.Selection.Move(ref unit,ref count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[2].Text);

wApp.Selection.Move(ref unit,ref count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[3].Text);

wApp.Selection.Move(ref unit,ref count);
wApp.Selection.TypeText(gridEX1.GetRow(i).Cells[4].Text);
//换行
wApp.Selection.MoveRight(ref unit,ref count,ref extend);
}
}
}
#endregion

　　然后就OK了，在对标签表控制要注意列循环和换行.

　　C#操作Excel（导入导出）

　　有很多朋友说需要C#导出到Excel的代码，现共享给大家

///
/// 读取Excel文档
///
/// 文件名称
/// 返回一个数据集
public DataSet ExcelToDS(string Path)
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +"Data Source="+ Path +";"+"Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
DataSet ds = null;
strExcel="select * from [sheet1$]";
myCommand = new OleDbDataAdapter(strExcel, strConn);
ds = new DataSet();
myCommand.Fill(ds,"table1");
return ds;
}

///
/// 写入Excel文档
///
/// 文件名称
public bool SaveFP2toExcel(string Path)
{
try
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +"Data Source="+ Path +";"+"Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
System.Data.OleDb.OleDbCommand cmd=new OleDbCommand ();
cmd.Connection =conn;
//cmd.CommandText ="UPDATE [sheet1$] SET 姓名='2005-01-01' WHERE 工号='日期'";
//cmd.ExecuteNonQuery ();
for(int i=0;i {
if(fp2.Sheets [0].Cells[i,0].Text!="")
{
cmd.CommandText ="INSERT INTO [sheet1$] (工号,姓名,部门,职务,日期,时间) VALUES('"+fp2.Sheets [0].Cells[i,0].Text+ "','"+
fp2.Sheets [0].Cells[i,1].Text+"','"+fp2.Sheets [0].Cells[i,2].Text+"','"+fp2.Sheets [0].Cells[i,3].Text+
"','"+fp2.Sheets [0].Cells[i,4].Text+"','"+fp2.Sheets [0].Cells[i,5].Text+"')";
cmd.ExecuteNonQuery ();
}
}
conn.Close ();
return true;
}
catch(System.Data.OleDb.OleDbException ex)
{
System.Diagnostics.Debug.WriteLine ("写入Excel发生错误："+ex.Message );
}
return false;
}

　　这种方法是相当有效的。

　　VB.NET实现word打开与关闭
Imports Word

'打开

Dim mWordapp As Word.Application 'word 应用程序

Dim mobjDoc As Word.Document 'word 文档

Dim fullFileName as string '文件路径

mWordapp = CreateObject("Word.Application")

mobjDoc = mWordapp.Documents.Add(FullFileName)

'关闭

If Not mobjDoc Is Nothing Then

'垃圾回收

mobjDoc = Nothing

End If

If Not mWordapp Is Nothing Then

System.Runtime.InteropServices.Marshal.ReleaseComObject(mWordapp)

mWordapp = Nothing
