UNITY3D讀寫CVS格式文件錄製(zhì)與存儲數據手套數據
2019/11/12 點擊(jī):
說明:
1.寫(xiě)入一個單(dān)元格時,如果含有逗號(hào),則需要將整個字段用雙引號括(kuò)起(qǐ)來(lái);如果裏麵還有雙引號就替換成兩個雙引號。
2.寫入一行時,末尾要加上\r\n作(zuò)為行分隔符。3.讀取時,也要根據上麵(miàn)的寫入規則進行解析。
直接看代碼:
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;public class CSVTool { private static char _csvSeparator = ',';
private static bool _trimColumns = false; //獲取一個(gè)單元格的寫入格式
public static string GetCSVFormat(string str)
{
string tempStr = str;
if (str.Contains(","))
{
if (str.Contains("\""))
{
tempStr = str.Replace("\"", "\"\"");
}
tempStr = "\"" + tempStr + "\"";
}
return tempStr;
} //獲取一行的寫入格式
public static string GetCSVFormatLine(ListstrList)
{
string tempStr = "";
for (int i = 0; i < strList.Count - 1; i++)
{
string str = strList[i];
tempStr = tempStr + GetCSVFormat(str) + ",";
}
tempStr = tempStr + GetCSVFormat(strList[strList.Count - 1]) + "\r\n";
return tempStr;
} //解析一行
public static ListParseLine(string line)
{
StringBuilder _columnBuilder = new StringBuilder();
ListFields = new List();
bool inColumn = false; //是否是在一個列元素裏
bool inQuotes = false; //是否需要轉義
bool isNotEnd = false; //讀取完畢未(wèi)結束(shù)轉義
_columnBuilder.Remove(0, _columnBuilder.Length);
//空行(háng)也是一個空元素,一個逗號是2個空元素
if (line == "")
{

// Iterate through every character in the line

關於UNITY的路徑有4個類型:
Application.dataPath:該路徑指向(xiàng)我們Unity編輯器的Asset文件夾
Application.persistentDataPath:該路(lù)徑指向ioses和androids的沙盒(hé)路徑
Application.streamingAssetsPath:streamingAsset文件(jiàn)夾路徑,在任何平台都(dōu)可以通過(guò)這個路徑讀取到文件夾裏的內(nèi)容
Application.temporaryCachePath:臨時數據文件路徑
