# Levenshtien Distance c# with Invoke code

Hello, I am trying to implement the Levenshtien distance algorithm in c# using the invoke code activity. I am new to using invoke code and c# in general. The c# implementation of the Levenshtien algorithm can be found below:

public static int EditDistance (string original, string modified)
{
int len_orig = original.Length;
int len_diff = modified.Length;

``````var matrix = new int[len_orig + 1, len_diff + 1];
for (int i = 0; i <= len_orig; i++)
matrix[i,0] = i;
for (int j = 0; j <= len_diff; j++)
matrix[0,j] = j;

for (int i = 1; i <= len_orig; i++) {
for (int j = 1; j <= len_diff; j++) {
int cost = modified[j - 1] == original[i - 1] ? 0 : 1;
var vals = new int[] {
matrix[i - 1, j] + 1,
matrix[i, j - 1] + 1,
matrix[i - 1, j - 1] + cost
};
matrix[i,j] = vals.Min ();
if (i > 1 && j > 1 && original[i - 1] == modified[j - 2] && original[i - 2] == modified[j - 1])
matrix[i,j] = Math.Min (matrix[i,j], matrix[i - 2, j - 2] + cost);
}
}
return matrix[len_orig, len_diff];
``````

}

How would I adapt this code to work with the invoke code activity?

Hi,

Hope the following sample helps you.

Hey

why to use c# code?

you can simply import the created library and just use it

Regards!

Other components of the project necessitate the use of c#
