如何检查特定字符串是否存在于字节数组中?

How to check whether a particular string is present in a byte array?

    var PDF = new ActionAsPdf("TestReport", null)
    {
            FileName = "TestFile.pdf",
            PageOrientation = Rotativa.Options.Orientation.Landscape,
            PageMargins = { Left = 1, Right = 1 }
    };
    byte[] PDFData = PDF.BuildPdf(ControllerContext);

是否可以检查 'PDFData' 中的字符串(例如 "Daily Task")? 请指导我。谢谢!

尝试将 byte 数组转换为 string:

var str = System.Text.Encoding.Default.GetString(PDFData);
var isContains = str.Contains("Daily Task");

一个例子:

string dailyTask = " Daily Task ";
byte[] PDFData = Encoding.ASCII.GetBytes(dailyTask);
var str = System.Text.Encoding.Default.GetString(PDFData);
var isContains = str.Contains("Daily Task");
Console.WriteLine(isContains);
