使用 Aspose.Cells 计算 IFNA 函数

Aspose.Cells 支持IFNA Excel函数的计算。如果公式返回#N/A 错误值，IFNA 函数返回您指定的值；否则返回公式的结果。

使用 Aspose.Cells 计算 IFNA 函数

下面的示例代码说明了Aspose.Cells对IFNA函数的计算。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Create new workbook
Workbook workbook = new Workbook();

// Access first worksheet
Worksheet worksheet = workbook.Worksheets[0];

// Add data for VLOOKUP
worksheet.Cells["A1"].PutValue("Apple");
worksheet.Cells["A2"].PutValue("Orange");
worksheet.Cells["A3"].PutValue("Banana");

// Access cell A5 and A6
Cell cellA5 = worksheet.Cells["A5"];
Cell cellA6 = worksheet.Cells["A6"];

// Assign IFNA formula to A5 and A6
cellA5.Formula = "=IFNA(VLOOKUP(\"Pear\",$A$1:$A$3,1,0),\"Not found\")";
cellA6.Formula = "=IFNA(VLOOKUP(\"Orange\",$A$1:$A$3,1,0),\"Not found\")";

// Caclulate the formula of workbook
workbook.CalculateFormula();

// Print the values of A5 and A6
Console.WriteLine(cellA5.StringValue);
Console.WriteLine(cellA6.StringValue);
