C# 等效于 VB.NET ReadFile 函数

Question

I have the following in VB.Net

ReadFile(HidDevice, ReadBuffer(0), (long)(Capabilities.InputReportByteLength), NumberOfBytesToRead, 0);

Was wondering what is the equivalent method in C#?

Answer 1

 using (System.IO.StreamReader streamReader = new System.IO.StreamReader("file location"))
        {
            string content = streamReader.ReadToEnd();
        }

OR

 using (System.IO.FileStream fileStream = new System.IO.FileStream("file location", System.IO.FileMode.Open))
        {
            byte[] content = new byte[fileStream.Length];
            fileStream.Read(content, 0, content.Length);
        }
