Convert a String to a Byte Array

[ShankarJ]

Hi!

I am quite new to C# and am writing a COM wrapper for a .NET Control. One of the functions requires a Byte array as input and I am having problems passing a SafeArray from the calling application. The String object has a ToCharArray() method but none to convert to Byte array. Do I have to go through all the string characters and assign a VAL(SubStringChar) to the Byte array?

Regards

Hi Jason,

That means there is no other easier or proper way.

Hi!

Should have googled before asking here. Anyway, the solution is ::

// C# to convert a string to a byte array.
public static byte[] StrToByteArray(string str)
{
    System.Text.ASCIIEncoding  encoding=new System.Text.ASCIIEncoding();
    return encoding.GetBytes(str);
}

// C# to convert a byte array to a string.
byte [] dBytes = ...
string str;
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
str = enc.GetString(dBytes);
