运行时出现错误 CS1002 - Markdown 解析器（仅限标题）

Question

"src/Solution.cs(9,12): error CS1002: ; expected"

I cannot work out why I am being shown this error? I have put my code below. I am very inexperienced at c-sharp, I normally work in c++, so maybe a small syntax error somewhere?

public class Challenge
{
  public static string MarkdownParser( string markdown )
  {
    
        string inputText = markdown;
        string outputText;
        
        unsigned int indexOfFirstSpace = 0;
        unsigned int inputTextLength = 0;
        
        //Trim Spaces Before & After String
        inputText = inputText.Trim();
    
        if (inputText.StartsWith("#")){
        
        //Find Index oF First Space & Store
        indexOfFirstSpace = inputText.IndexOf(" ");
          
        if (indexOfFirstSpace > 6){
          return inputText;
        }
          
        else{
        
        //Find Length Of Input String
        inputTextLength = inputText.Length;
        
        //Store Hashes In Own String
        string hashes = inputText.Substring(0, indexOfFirstSpace);
        
        //Store header text in string
        string headerText = inputText.Substring(indexOfFirstSpace,(inputTextLength - indexOfFirstSpace));
    
        //Trim Spaces From Front
        headerText = headerText.TrimStart();
        
        //Build Output
        outputText = "<h" + indexOfFirstSpace + ">" + headerText + "</h" + indexOfFirstSpace + ">";
        
        return outputText;
        }
    }
    
          else {
            return inputText;
          }
  }
}

There are 2 problems here:

1. You tried to use 'unsigned int'. in C# the keyword for that is uinit.

2. The returned type for inputText.Length is actually an int, so the fixed code should be:

   public class Challenge { public static string MarkdownParser(string markdown) {

    string inputText = markdown; string outputText; // ---- Changed these variables to Int ---- int indexOfFirstSpace = 0; int inputTextLength = 0; //Trim Spaces Before & After String inputText = inputText.Trim(); if (inputText.StartsWith("#")) { //Find Index oF First Space & Store indexOfFirstSpace = inputText.IndexOf(" "); if (indexOfFirstSpace > 6) { return inputText; } else { //Find Length Of Input String inputTextLength = inputText.Length; //Store Hashes In Own String string hashes = inputText.Substring(0, indexOfFirstSpace); //Store header text in string string headerText = inputText.Substring(indexOfFirstSpace, (inputTextLength - indexOfFirstSpace)); //Trim Spaces From Front headerText = headerText.TrimStart(); //Build Output outputText = "<h" + indexOfFirstSpace + ">" + headerText + "</h" + indexOfFirstSpace + ">"; return outputText; } } else { return inputText; } }
