读取字节数组Textbox - > byte []

Question

I've got Textbox with a string like 89 3d 2c c0 7f 00

How to store it to Byte[] (byte array) variable ?

Now I can read only one dec value :(

Value=BitConverter.GetBytes(Int32.Parse(this.textBox3.Text.ToString()));

Answer 1

Use textBox3.Text.Split() to get an array of strings, each of length 2.

Then use byte.Parse(part, NumberStyles.HexNumber) in a loop to convert each part from hexadecimal to an integer.

Using LINQ it can be written like this:

byte[] result = textBox3.Text.Split(' ')
    .Select(part => byte.Parse(part, System.Globalization.NumberStyles.HexNumber))
    .ToArray();
