第七章：關(guān)于工作表的使用

▲第二節(jié)：創(chuàng)建和管理工作表

Aspose.Cells提供了一個(gè) 代表Excel文件的Workbook類。該Workbook類包含一個(gè)工作表 集合允許訪問(wèn)在Excel文件中的每個(gè)工作表

將工作表添加到新的Excel文件

• 建工作簿 類的對(duì)象。
• 調(diào)用WorksheetCollection 類的Add 方法。一個(gè)空的工作表將自動(dòng)添加到Excel文件中。可以通過(guò)將新工作表的工作表索引傳遞到Worksheets集合進(jìn)行引用。
• 獲取工作表參考。
• 在工作表上執(zhí)行工作。
• 通過(guò)調(diào)用Workbook 類的Save 方法，用新的工作表保存新的Excel文件。

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Create directory if it is not already present.
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);

// Instantiating a Workbook object
Workbook workbook = new Workbook();

// Adding a new worksheet to the Workbook object
int i = workbook.Worksheets.Add();

// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[i];

// Setting the name of the newly added worksheet
worksheet.Name = "My Worksheet";

// Saving the Excel file
workbook.Save(dataDir + "output.out.xls");

將工作表添加到設(shè)計(jì)器電子表格

將工作表添加到設(shè)計(jì)器電子表格的過(guò)程與添加新工作表的過(guò)程相同，除了Excel文件已經(jīng)存在，因此應(yīng)在添加工作表之前將其打開。可以通過(guò)Workbook 類打開設(shè)計(jì)器電子表格。

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

string InputPath = dataDir + "book1.xlsx";

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(InputPath, FileMode.Open);

           
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);


// Adding a new worksheet to the Workbook object
int i = workbook.Worksheets.Add();

// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[i];

// Setting the name of the newly added worksheet
worksheet.Name = "My Worksheet";

// Saving the Excel file
workbook.Save(dataDir + "output.xlsx");

使用工作表名稱訪問(wèn)工作表

通過(guò)指定其名稱或索引來(lái)訪問(wèn)任何工作表。

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

string InputPath = dataDir + "book1.xlsx";

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(InputPath, FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Accessing a worksheet using its sheet name
Worksheet worksheet = workbook.Worksheets["Sheet1"];
Cell cell = worksheet.Cells["A1"];
Console.WriteLine(cell.Value);

使用工作表名稱刪除工作表

要從文件中刪除工作表，請(qǐng)調(diào)用WorksheetCollection 類的 RemoveAt 方法。將工作表名稱傳遞給RemoveAt 方法以刪除特定的工作表。

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Removing a worksheet using its sheet name
workbook.Worksheets.RemoveAt("Sheet1");

// Save workbook
workbook.Save(dataDir + "output.out.xls");

使用工作表索引刪除工作表

當(dāng)已知工作表的名稱時(shí)，按名稱刪除工作表效果很好。如果您不知道工作表的名稱，請(qǐng)使用RemoveAt 方法的重載版本，該方法使用工作表的工作表索引而不是工作表名稱。

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Removing a worksheet using its sheet index
workbook.Worksheets.RemoveAt(0);

// Save workbook
workbook.Save(dataDir + "output.out.xls");
