VB EPPLUS 4.5.3 复制表格A1:C32区域内容到剪切板

以下是VB EPPLUS 4.5.3复制表格A1:C32区域内容到剪切板的代码：

Imports OfficeOpenXml
Imports System.IO
Imports System.Windows.Forms

Public Sub CopyToClipboard()
    Dim filePath As String = "C:\example.xlsx" '替换为实际文件路径
    Dim fileInfo As New FileInfo(filePath)
    Using package As New ExcelPackage(fileInfo)
        Dim worksheet As ExcelWorksheet = package.Workbook.Worksheets("Sheet1") '替换为实际工作表名称
        Dim range As ExcelRange = worksheet.Cells("A1:C32")
        Clipboard.SetText(range.Copy().ToString())
    End Using
End Sub

请注意，此代码需要引用EPPlus库，可以通过NuGet包管理器安装。

EPPLUS 4.5.3 复制表格

在EPPLUS 4.5.3中，可以通过以下步骤复制表格：

1. 获取要复制的源表格的范围，例如：

   ExcelRange sourceRange = worksheet.Cells["A1:D4"];

2. 使用`Copy`方法创建源表格的副本：

   ExcelRange copiedRange = sourceRange.Copy();

3. 将副本表格的范围设置为目标位置，例如：

   copiedRange.AutoFitColumns();
   copiedRange.AutoFitRows();
   copiedRange.Style.Border.BorderAround(ExcelBorderStyle.Thin);
   copiedRange.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
   worksheet.Cells["F1"].LoadFromText("Copied Table:");
   worksheet.Cells["F2"].LoadFromText(" ");
   worksheet.Cells["F3"].LoadFromText(" ");
   worksheet.Cells["F4"].LoadFromText(" ");
   worksheet.Cells["F1"].Style.Font.Bold = true;
   worksheet.Cells["F1:F4"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
   copiedRange.CopyTo(worksheet.Cells["G1"]);

在这里，我们将副本表格的样式自适应列和行的宽度和高度，将单元格边框设置为细线条，水平居中和垂直居中。然后，我们将副本表格的范围复制到目标位置（这里是单元格“G1”）。

完整的示例代码如下：

using OfficeOpenXml;
using OfficeOpenXml.Style;

class Program
{
    static void Main(string[] args)
    {
        using (ExcelPackage package = new ExcelPackage())
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet1");

            // Create source table
            worksheet.Cells["A1"].Value = "Header1";
            worksheet.Cells["B1"].Value = "Header2";
            worksheet.Cells["C1"].Value = "Header3";
            worksheet.Cells["D1"].Value = "Header4";
            worksheet.Cells["A2"].Value = "Data1";
            worksheet.Cells["B2"].Value = "Data2";
            worksheet.Cells["C2"].Value = "Data3";
            worksheet.Cells["D2"].Value = "Data4";
            worksheet.Cells["A3"].Value = "Data5";
            worksheet.Cells["B3"].Value = "Data6";
            worksheet.Cells["C3"].Value = "Data7";
            worksheet.Cells["D3"].Value = "Data8";
            worksheet.Cells["A4"].Value = "Data9";
            worksheet.Cells["B4"].Value = "Data10";
            worksheet.Cells["C4"].Value = "Data11";
            worksheet.Cells["D4"].Value = "Data12";

            // Copy source table
            ExcelRange sourceRange = worksheet.Cells["A1:D4"];
            ExcelRange copiedRange = sourceRange.Copy();
            copiedRange.AutoFitColumns();
            copiedRange.AutoFitRows();
            copiedRange.Style.Border.BorderAround(ExcelBorderStyle.Thin);
            copiedRange.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;

            // Paste copied table
            worksheet.Cells["F1"].LoadFromText("Copied Table:");
            worksheet.Cells["F2"].LoadFromText(" ");
            worksheet.Cells["F3"].LoadFromText(" ");
            worksheet.Cells["F4"].LoadFromText(" ");
            worksheet.Cells["F1"].Style.Font.Bold = true;
            worksheet.Cells["F1:F4"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
            copiedRange.CopyTo(worksheet.Cells["G1"]);

            package.SaveAs(new FileInfo("output.xlsx"));
        }
    }
}

cv2.error: opencv(4.5.3) :-1: error: (-5:bad argument) in function 'puttext'

此错误是由于在使用OpenCV中的 putText 函数时，存在参数错误所导致的。具体错误信息为“bad argument”，意为参数不正确。需要检查 putText 函数的参数是否正确，并进行相应的调整。
