c# - 在 EPPlus 4.5.3 中阅读形状和文本框

Question

我正在尝试使用 EPPlus 版本 4.5.3 读取 excel 文件，我可以使用以下代码来执行此操作:

FileInfo existingFile = new FileInfo(FilePath);
using (ExcelPackage package = new ExcelPackage(existingFile))
{
    //get the first worksheet in the workbook
    ExcelWorksheet worksheet = package.Workbook.Worksheets[1];
    int colCount = worksheet.Dimension.End.Column;  //get Column Count
    int rowCount = worksheet.Dimension.End.Row;     //get row count
    for (int row = 1; row <= rowCount; row++)
    {
        for (int col = 1; col <= colCount; col++)
        {
            Console.WriteLine(" Row:" + row + " column:" + col + " Value:" + worksheet.Cells[row, col].Value?.ToString().Trim());
        }
    }
}

现在，我被困在的地方是形状。因此，我需要阅读的 excel 文件中有形状，这些形状中有我正在尝试阅读的文本。我曾尝试在互联网上搜索此问题，但似乎找不到任何内容。
我怎样才能读取这些数据？到目前为止我尝试过的代码:

foreach (var drawing in sheet.Drawings)
{
    var type = drawing.GetType();
    var data = drawing.ToString();
    Console.WriteLine("Drawing Type:" + type + " Data: " + data);
}

Answer 1

我今天刚遇到这个问题并想通了。您必须首先迭代 worksheet.Drawings 集合以确定是否有任何图纸是“形状”。根据我对 Excel VBA 的了解，您不能将文本放在图像/图片上，它必须是一个形状。如果我错了，有人可以纠正我。

using (ExcelPackage excelPackage = new ExcelPackage(stream))
{
    ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets[1];
    foreach (ExcelDrawing dw in worksheet.Drawings)
    {
        if (dw.GetType().ToString() == "OfficeOpenXml.Drawing.ExcelShape")
        {
            ExcelShape shape = (ExcelShape)dw;
            if (shape.RichText != null && shape.RichText.Count > 0)
            {
                foreach (ExcelParagraph item in shape.RichText)
                {
                    Console.WriteLine("{0} - Rich Text Line: {1}", dw.Name, item.Text);
                }
            }
        }
        else
            { Console.WriteLine("{0} is not a shape, its a {1}", dw.Name, dw.GetType().ToString()); }
    }
}

从那里应该很容易跳转来修改图片中的文本:

item.RichText[1].Text = "Updated Text";

输出:

Picture 1 is not a shape, its a OfficeOpenXml.Drawing.ExcelPicture
TextBox 1 - Rich Text Line: Inventory List
TextBox 1 - Rich Text Line: Some Company
