第七章：关于工作表的使用

▲第二节：创建和管理工作表

Aspose.Cells提供了一个 代表Excel文件的Workbook类。该Workbook类包含一个工作表 集合允许访问在Excel文件中的每个工作表

将工作表添加到新的Excel文件

• 建工作簿 类的对象。
• 调用WorksheetCollection 类的Add 方法。一个空的工作表将自动添加到Excel文件中。可以通过将新工作表的工作表索引传递到Worksheets集合进行引用。
• 获取工作表参考。
• 在工作表上执行工作。
• 通过调用Workbook 类的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");

将工作表添加到设计器电子表格

将工作表添加到设计器电子表格的过程与添加新工作表的过程相同，除了Excel文件已经存在，因此应在添加工作表之前将其打开。可以通过Workbook 类打开设计器电子表格。

// 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");

使用工作表名称访问工作表

通过指定其名称或索引来访问任何工作表。

// 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);

使用工作表名称删除工作表

要从文件中删除工作表，请调用WorksheetCollection 类的 RemoveAt 方法。将工作表名称传递给RemoveAt 方法以删除特定的工作表。

// 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");

使用工作表索引删除工作表

当已知工作表的名称时，按名称删除工作表效果很好。如果您不知道工作表的名称，请使用RemoveAt 方法的重载版本，该方法使用工作表的工作表索引而不是工作表名称。

// 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");
