Good evening, I was working on a graphic adventure and I want to make a random function with a 4 digit code, turns out that as I am a very novice programmer, I crashed with an inconvenient
private void CheckResults()
{
if (codeSequence = RandomCode.RanCode.ToString())
{
SoundManager.PlaySound("nice");
}
else
{
SoundManager.PlaySound("wrong");
}
"RandomCode.RanCode" is a int void, and adding "ToString" will shot an error saying
"RanCode is a method which is not valid in the given context"
This is the RandomCode void:
public void RanCode()
{
Code = Random.Range(1111, 9999);
}
If anyone out there has any ideas or solves, I will be eternally grateful

There's no such thing as an "int void". A method either returns nothing (void) or returns a value (in your case you seem to expect int).
// Returns nothing
// |
// v
public void RanCode()
{
// assigns result of `Range` to `Code` property/field
Code = Random.Range(1111, 9999);
}
If you want to also return the value, you need to rewrite your method like this:
public int RanCode()
{
Code = Random.Range(1111, 9999);
return Code;
}
You do have another issue here:
RandomCode.RanCode.ToString()
To call a method you need (), so it should be this:
RandomCode.RanCode().ToString()
Also, for equality checks you want == not = (which is assignment).
I do wonder why you're assigning a value to Code here. If we use your existing code (without my fix above), I guess that perhaps you intended something like this instead?:
private void CheckResults()
{
RandomCode.RanCode();
if (codeSequence == RandomCode.Code.ToString())
{
SoundManager.PlaySound("nice");
}
else
{
SoundManager.PlaySound("wrong");
}
}

Good morning,
I am doing a page for my intership and I found this function but it isn't working, can someone help?
Thank you in advance.
string _id = this.txtIdGrupo.Text;
if (!Regex.IsMatch(_id, #"^\d+$"))
return false;
The output says this:
error CS0103: The name 'Regex' does not exist in the current context

this is not an issue with the bit of code you showed.
This is a namespace issue at the very top of your file.
The solution should be https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/namespaces/
using System;
using System.Text.RegularExpressions;
public class Test
{
public static void Main ()
{
var isNumeric1 = IsNumeric("1");
Console.WriteLine(isNumeric1);
var isNumeric2 = IsNumeric("HelloWorld");
Console.WriteLine(isNumeric2);
//call IsNumeric with the value of this.txtIdGrupo.Text like this
//var isNumeric = IsNumeric(this.txtIdGrupo.Text);
}
private static bool IsNumeric(string str)
{
string id = str;
if (!Regex.IsMatch(id, #"^\d+$"))
return false;
return true;
}
}
See it in action:
https://dotnetfiddle.net/I7cAKs
notice the "using System.Text.RegularExpressions"
Using tools like Resharper and similar will definitely give you hints and will improve your day to day !

Make sure you have the System.Text.RegularExpressions
is imported

Can Someone tell me what's wrong with my code? It's telling me that there is no Method suitable for an entry point.
CS5001 Program does not contain a static 'Main' method suitable for an entry point.

Method names are case sensitive. The method should be called Main, with a capital M, not main like you currently have:
static void Main(string[] args)

I am creating a 2d platform game in the Unity Engine Version Num - 2018.4.9f1 with c# compiled with Visual Studio Version Num - 1.38.1.
The console in Unity Engine is showing two errors listed below with the code I have in the Visual Studio.
error CS1003: Syntax error, '(' expected
error CS1031: Type expected
My code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
[RequireComponent(typeof)(Text))]
public class CountdownText : MonoBehaviour {
public delegate void CountdownFinished();
public static event CountdownFinished OnCountdownFinished;
Text countdown;
void OnEnable() {
countdown = GetComponent<Text>();
countdown.text = "3";
StartCoroutine("Countdown");
}
IEnumerator Countdown() {
int count = 3;
for (int i = 0; i < count; i++) {
countdown.text = (count - i).ToString();
yield return new WaitForSeconds(1);
}
OnCountdownFinished();
}
}

RequireComponent(typeof)(Text)) is wrong. It should be RequireComponent(typeof(Text))
The typeof operator obtains the System.Type instance for a type.

im kinda new to C# and i got a code that uses public static bool.
But how do i check it?
I tried to do this
public static bool CheckForInternetConnection()
{
try
{
using (var client = new WebClient())
{
using (var stream = client.OpenRead("http://www.google.com"))
{
return true;
}
}
}
catch
{
return false;
}
}
private async void Form1_Load(object sender, EventArgs e)
{
await Task.Delay(5000);
if (CheckForInternetConnection() = true)
{
}
}
And it gave me an error.

I confirm the comments: it's only a syntax error due to the lack of the 2nd = char in the if(...) conditional block. I've tested your code in a console project on the run and, with the 2nd = it works fine.
