Simply use this method hope it solves your problem:
public static string StripTagsCharArray(string source)
{
char[] array = new char[source.Length];
int arrayIndex = 0;
bool inside = false;
for (int i = 0; i < source.Length; i++)
{
char let = source[i];
if (let == '<')
{
inside = true; continue;
}
if (let == '>')
{
inside = false; continue;
}
if (!inside)
{
array[arrayIndex] = let; arrayIndex++;
}
}
return new string(array, 0, arrayIndex);
}
Call it like:
string convertedString = StripTagsCharArray(strHTML);
