有沒有辦法使用EPPlus獲得'命名'單元格？

Question

我有一個Excel文件，我用EPPlus以編程方式填充。

我曾嘗試以下：

// provides access to named ranges, does not appear to work with single cells 
worksheet.Names["namedCell1"].Value = "abc123"; 

// provides access to cells by address 
worksheet.Cells["namedCell1"].Value = "abc123"; 

下不工作 - 所以我知道我至少接近。

worksheet.Cells["A1"].Value = "abc123";

其實，它有點誤導。命名範圍存儲在workBOOK級別，而不是workSHEET級別。所以，如果你做這樣的事情：

[TestMethod] 
public void Get_Named_Range_Test() 
{ 
    //http://stackoverflow.com/questions/30494913/is-there-a-way-to-get-named-cells-using-epplus 

    var existingFile = new FileInfo(@"c:\temp\NamedRange.xlsx"); 
    using (var pck = new ExcelPackage(existingFile)) 
    { 
     var wb = pck.Workbook; //Not workSHEET 
     var namedCell1 = wb.Names["namedCell1"]; 

     Console.WriteLine("{{\"before\": {0}}}", namedCell1.Value); 
     namedCell1.Value = "abc123"; 
     Console.WriteLine("{{\"after\": {0}}}", namedCell1.Value); 
    } 
} 

您在輸出得到這個（使用Excel與它的虛擬數據文件）：

{"before": Range1 B2} 
{"after": abc123}
