C# get all occurrences of a string

public List<Integer> findWordUpgrade(String textString, String word) {
    List<Integer> indexes = new ArrayList<Integer>();
    StringBuilder output = new StringBuilder();
    String lowerCaseTextString = textString.toLowerCase();
    String lowerCaseWord = word.toLowerCase();
    int wordLength = 0;

    int index = 0;
    while(index != -1){
        index = lowerCaseTextString.indexOf(lowerCaseWord, index + wordLength);  // Slight improvement
        if (index != -1) {
            indexes.add(index);
        }
        wordLength = word.length();
    }
