我无法编译以下代码,该代码已从C#翻译过来。

编译器产生了此错误:错误FS0010:在实现文件中此点或之前的不完整结构化构造。在此点或其他标记之前或之前的预期不完整结构化构造。

我认为问题在于缩进。在F#中,如果代码用相同数量的空格缩进,则代码适合一个块。

您应该在与ead_value_openxml函数的其余代码相同的缩进级别返回值。功能似乎也已缩进。试试这个:

//Read the value of a single cell by string coordinates (Open XML SDK)
let read_value_openxml file_path_and_name column row =
    let stream = new System.IO.FileStream(file_path_and_name, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite)

    // Open the spreadsheet document for read-only access.
    let document = SpreadsheetDocument.Open(stream, false)

    // Retrieve a reference to the workbook part.
    let wbPart = document.WorkbookPart

    // Find the sheet with the supplied name, and then use that sheet object to retrieve a reference to the first worksheet.
    let firstSheet:Sheet = wbPart.Workbook.Descendants<Sheet>().First()
    let theSheet:Worksheet = ((WorksheetPart.wbPart.GetPartById(firstSheet.Id)).Worksheet

    // Retrieve a reference to the worksheet part.
    let wsPart = wbPart.GetPartById(firstSheet.Id)

    // Use its Worksheet property to get a reference to the cell whose address matches the address you supplied.
    let theCell = wsPart.Worksheet.Descendants<Cell>().Where(fun c -> c.CellReference = column + row).FirstOrDefault()

    // Return a value
    theCell.InnerText
