异常描述，使用Aspose.Cells导出电子表格文件异常：
No data is available for encoding 936. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.

解决办法：

添加如下代码

//注册编码提供程序 
System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);

完整代码参考：

public static void ExportExcel(List<List<object>> data, string outPath)

	//注册编码提供程序
	System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);

	Aspose.Cells.Workbook wb = new Aspose.Cells.Workbook();
	Aspose.Cells.Worksheet sheet = wb.Worksheets[0];
	Aspose.Cells.Cells cells = sheet.Cells;
	Aspose.Cells.Style style = wb.Styles[wb.Styles.Add()];
	//style.Font.Name = "宋体";
	style.Font.Size = 12;
	cells.ApplyStyle(style, new StyleFlag()  All = true );
	int cols = data[0].Count;

	//标题样式
	Aspose.Cells.Style styleTitle = wb.Styles[wb.Styles.Add()];
	styleTitle.Font.IsBold = true;
	styleTitle.Font.Size = 12;
	Aspose.Cells.Range range = cells.CreateRange(0, 0, 1, cols);
	range.ApplyStyle(styleTitle, new StyleFlag()  All = true );

	object[,] dataArr2 = new object[data.Count, cols];
	for (int n = 0; n < data.Count; n++)
	
		var rowLine = data[n];
		for (int j = 0; j < rowLine.Count; j++)
		
			dataArr2[n, j] = rowLine[j];
		
	

	cells.ImportTwoDimensionArray(dataArr2, 0, 0);
