Find and Replace text in all Game Objects in a Unity Project

I have a couple of asks to update some text throughout a project. Doing a find and replace in code is easy, but I would like to implement a tool to look through all game objects. Unfortunately, I can grab all of the game objects in the scene, but I have not found a solution to grab all of the game objects in the project. Does anyone have any suggestions?
This is my current approach:
using System;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using EditorPlayerSettings = UnityEditor.PlayerSettings;
namespace UnityEditor.XCodeEditor
{
public class FindAndReplaceToolbar : EditorWindow
{
private const string TAG = "FindAndReplace";
string mOldValue = string.Empty;
string mNewValue = string.Empty;
[MenuItem("Window/Find And Replace")]
void Init()
{
var window = GetWindow<FindAndReplaceToolbar>(false, "Find And Replace Toolbar");
window.minSize = new Vector2(10, 10);
window.Show();
}
void OnGUI()
{
GUILayout.BeginHorizontal();
{
mOldValue = EditorGUILayout.TextField("Find: ", mOldValue, GUILayout.ExpandWidth(true));
}
GUILayout.EndHorizontal();
GUILayout.BeginHorizontal();
{
mNewValue = EditorGUILayout.TextField("Replace: ", mNewValue, GUILayout.ExpandWidth(true));
}
GUILayout.EndHorizontal();
GUILayout.BeginHorizontal();
if (GUILayout.Button("Find and Replace"))
{
FindAndReplace();
}
GUILayout.EndHorizontal();
}
#region Find And Replace Helper
public void FindAndReplace()
{
Debug.Log($"{TAG} Started: ({mOldValue} - {mNewValue})");
foreach (var textMeshProUGUI in GetAllTextMeshProUGUIsInScene())
{
if (textMeshProUGUI.text.Contains(mOldValue))
{
Debug.Log($"{TAG} Replaced {mOldValue} in {textMeshProUGUI.name} with {mNewValue} (See {GetFileName(textMeshProUGUI.transform)})");
textMeshProUGUI.text = textMeshProUGUI.text.Replace(mOldValue, mNewValue);
}
}
Debug.Log($"{TAG} Finished: ({mOldValue} - {mNewValue})");
}
public List<TextMeshProUGUI> GetAllTextMeshProUGUIsInScene()
{
List<TextMeshProUGUI> objectsInScene = new List<TextMeshProUGUI>();
foreach (TextMeshProUGUI go in (TextMeshProUGUI[]) Resources.FindObjectsOfTypeAll(typeof(TextMeshProUGUI)))
{
if (!EditorUtility.IsPersistent(go.transform.root.gameObject) && !(go.hideFlags == HideFlags.NotEditable || go.hideFlags == HideFlags.HideAndDontSave))
{
objectsInScene.Add(go);
}
}
return objectsInScene;
}

{
try

var parent = transform;
while (parent.parent != null)
{

}

How to find items in a ListBox?

I am creating an application where I have a ListBox which has items that are read in from a text file using StreamReader. I have created a search form but I'm not sure what to do next. Can anyone give me some suggestions please? Here is my code:
My code for the ListBox (sorry it's so long)
public partial class frmSwitches : Form
{
public static ArrayList switches = new ArrayList();
public static frmSwitches frmkeepSwitches = null;
public static string inputDataFile = "LeckySafe.txt";
const int numSwitchItems = 6;
public frmSwitches()
{
InitializeComponent();
frmkeepSwitches = this;
}
private void btnDevices_Click(object sender, EventArgs e)
{
frmDevices tempDevices = new frmDevices();
tempDevices.Show();
frmkeepSwitches.Hide();
}
private bool fileOpenForReadOK(string readFile, ref StreamReader dataIn)
{
try
{
dataIn = new StreamReader(readFile);
return true;
}
catch (FileNotFoundException notFound)
{
MessageBox.Show("ERROR Opening file (when reading data in) - File could not be found.\n"
+ notFound.Message);
return false;
}
catch (Exception e)
{
MessageBox.Show("ERROR Opening File (when reading data in) - Operation failed.\n"
+ e.Message);
return false;
}
}
private bool getNextSwitch(StreamReader inNext, string[] nextSwitchData)
{
string nextLine;
int numDataItems = nextSwitchData.Count();
for (int i = 0; i < numDataItems; i++)
{
try
{
nextLine = inNext.ReadLine();
if (nextLine != null)
nextSwitchData[i] = nextLine;
else
{
return false;
}
}
catch (Exception e)
{
MessageBox.Show("ERROR Reading from file.\n" + e.Message);
return false;
}
}
return true;
}
private void readSwitches()
{
StreamReader inSwitches = null;
Switch tempSwitch;
bool anyMoreSwitches = false;
string[] switchData = new string[numSwitchItems];
if (fileOpenForReadOK(inputDataFile, ref inSwitches))
{
anyMoreSwitches = getNextSwitch(inSwitches, switchData);
while (anyMoreSwitches == true)
{
tempSwitch = new Switch(switchData[0], switchData[1], switchData[2], switchData[3], switchData[4], switchData[5]);
switches.Add(tempSwitch);
anyMoreSwitches = getNextSwitch(inSwitches, switchData);
}
}
if (inSwitches != null) inSwitches.Close();
}
public static bool fileOpenForWriteOK(string writeFile, ref StreamWriter dataOut)
{
try
{
dataOut = new StreamWriter(writeFile);
return true;
}
catch (FileNotFoundException notFound)
{
MessageBox.Show("ERROR Opening file (when writing data out)" +
"- File could not be found.\n" + notFound.Message);
return false;
}
catch (Exception e)
{
MessageBox.Show("ERROR Opening File (when writing data out)" +
"- Operation failed.\n" + e.Message);
return false;
}
}
public static void writeSwitches()
{
StreamWriter outputSwitches = null;
if (fileOpenForWriteOK(inputDataFile, ref outputSwitches))
{
foreach (Switch currSwitch in switches)
{
outputSwitches.WriteLine(currSwitch.getSerialNo());
outputSwitches.WriteLine(currSwitch.getType());
outputSwitches.WriteLine(currSwitch.getInsDate());
outputSwitches.WriteLine(currSwitch.getElecTest());
outputSwitches.WriteLine(currSwitch.getPatId());
outputSwitches.WriteLine(currSwitch.getNumDevice());
}
outputSwitches.Close();
}
if (outputSwitches != null) outputSwitches.Close();
}
private void showListOfSwitches()
{
lstSwitch.Items.Clear();
foreach (Switch b in switches)
lstSwitch.Items.Add(b.getSerialNo()
+ b.getType() + b.getInsDate()
+ b.getElecTest() + b.getPatId() + b.getNumDevice());
}
My code for the search form:
private void btnSearch_Click(object sender, EventArgs e)
{
frmSearchSwitch tempSearchSwitch = new frmSearchSwitch();
tempSearchSwitch.Show();
frmkeepSwitches.Hide();
}

If using a List<T> and lambda is not possible for you then go no farther.
Here I use a List<T> for the data source of a ListBox and mocked up data as where the data comes from is not important but here I am focusing on searching on a property within a class where a select is used to index the items then the where searches in this case) for a specific item, if found the index is used to move to the item. No code present for if not located as this is easy for you to do if the code here is something that is doable for you.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
namespace ListBoxSearch_cs
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Button1_Click(object sender, EventArgs e)
{
var results =
((List<Item>)ListBox1.DataSource)
.Select((data, index) => new
{ Text = data.SerialNumber, Index = index })
.Where((data) => data.Text == "BB1").FirstOrDefault();
if (results != null)
{
ListBox1.SelectedIndex = results.Index;
}
}
private void Form1_Load(object sender, EventArgs e)
{
var items = new List<Item>() {
new Item {Identifier = 1, SerialNumber = "AA1", Type = "A1"},
new Item {Identifier = 2, SerialNumber = "BB1", Type = "A1"},
new Item {Identifier = 3, SerialNumber = "CD12", Type = "XD1"}
};
ListBox1.DisplayMember = "DisplayText";
ListBox1.DataSource = items;
}
}
/// <summary>

public class Item
{
public string SerialNumber { get; set; }

C# Using SoundPlayer to Pause and Resume

I am another person dabbling with C# and wanting to create a simple audio application that plays wav files loaded into the program via an upload program. My issue is that I need to get whatever audio file currently being played to pause with the track timer of the audio file being used when I start the audio file again via my Play button. I already have a global timer, 'baseTimer', that I think I can use to set the audio file, that was stopped, track duration point. However I do not know how to accomplish this nor do I really know how to use all of the mci commands yet.
I have displayed all of my code for my main application... I also have read that I may need to utilize threading, but I've also read that it would be impossible to set an audio files track duration with a thread.

Edit:
For clarity currentaudio has a file as such "music3.wav" or "talk1.wav" in it.

Super old question but just for anyone looking here's what worked for me:
double currentPos = audioplayer.CurrentPosition;
audioplayer.Play();
audioplayer.Seek(currentPos);

SoundPlayer is extremely limited, and doesn't support Pause and Resume. Are you able to use the WPF MediaElement instead? You will find it is much more powerful, supporting playing files of many types, repositioning, setting volume, pausing and resuming. You can also use it to get the file length instead of mci.

You probably don't have write access to C:\. Try changing the save path to "C:\Users\{YouName}\Documents\BikeData.txt" instead.
Or start Visual Studio with administrative privileges by right clicking on its icon and choosing "Run as Administrator"

File.WriteAllLines("C:\" + "BikeData.txt", SaveData);
File.WriteAllLine(string,string[]), through "SecurityException" when user does not have rights to write in a particular directrory or drive so you have to give write permission, refer this link File.WriteAllLines
