總得可以分兩步進行，步驟一、將DocViewer控制元件新增到VS工具箱；步驟二、建立一個Windows窗體應用程式。建立程式後，可透過資料夾或者流來載入開啟Word文件。

詳細操作如下：

1. 初始化Form1中的元件。

System.IO.FileStream stream;

public Form1()

{

InitializeComponent();

}

2. 建立一個OpenFileDialog來選擇我們想要載入的正確檔案型別，否則錯誤訊息“無法檢測到當前檔案型別”將會出現。

private void btnOpen_Click(object sender, EventArgs e)

{

OpenFileDialog dialog = new OpenFileDialog();

dialog.Filter = "Word97-2003 files(*.doc)|*.doc|Word2007-2010 files (*.docx)|*.docx|All files (*.*)|*.*";

dialog.Title = "Select a DOC file";

dialog.Multiselect = false;

dialog.InitialDirectory = System.IO.Path.GetFullPath(@"..\..\..\..\..\..\Data"); DialogResult result = dialog.ShowDialog();

if (result == DialogResult.OK)

{

try

{

this.docDocumentViewer1.LoadFromFile(dialog.FileName);

}

catch (Exception ex)

{

MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);

}

}

}

private void btnOpenStream_Click(object sender, EventArgs e)

{

OpenFileDialog dialog = new OpenFileDialog();

dialog.Filter = "Word97-2003 files(*.doc)|*.doc|Word2007-2010 files (*.docx)|*.docx|All files (*.*)|*.*";

dialog.Title = "Select a DOC file";

dialog.Multiselect = false;

dialog.InitialDirectory = System.IO.Path.GetFullPath(@"..\..\..\..\..\..\Data"); DialogResult result = dialog.ShowDialog();

if (result == DialogResult.OK)

{

try

{

string docFile = dialog.FileName;

stream = new System.IO.FileStream(docFile, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read);

if (stream != null)

{

this.docDocumentViewer1.LoadFromStream(stream, Spire.Doc.FileFormat.Auto);

}

}

catch (Exception ex)

{

MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);

}

}

}

4. 關閉開啟的檔案

private void btnClose_Click(object sender, EventArgs e)

{

this.docDocumentViewer1.CloseDocument();

}
