UNITY3D讀寫CVS格(gé)式文件錄製與(yǔ)存儲數據手套數據
2019/11/12 點擊:
說明:
1.寫入一(yī)個單元格時,如果含有逗號(hào),則需(xū)要將整個字(zì)段用雙引號括起來;如果(guǒ)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(yào)加上\r\n作為行分隔符。3.讀取時,也要根據上麵的寫入規則進(jìn)行解析。
直接看代碼(mǎ):

using System.Collections.Generic;
using System.IO;
using System.Text;public class CSVTool { private static char _csvSeparator = ',';
private static bool _trimColumns = false; //獲取一個單元格的寫(xiě)入格式

{
string tempStr = str;
if (str.Contains(","))
{
if (str.Contains("\""))
{
tempStr = str.Replace("\"", "\"\"");
}
tempStr = "\"" + tempStr + "\"";
}
return tempStr;
} //獲(huò)取一行的寫(xiě)入格式(shì)
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(sù)裏
bool inQuotes = false; //是否需要轉義
bool isNotEnd = false; //讀取完畢未結束轉義
_columnBuilder.Remove(0, _columnBuilder.Length);
//空(kōng)行(háng)也是一個空元素,一(yī)個逗(dòu)號是2個空元素

關於UNITY的路徑有4個類型:
Application.dataPath:該路徑指向我們Unity編輯器的Asset文件夾
Application.persistentDataPath:該路徑指向ioses和androids的沙盒路徑
Application.streamingAssetsPath:streamingAsset文件夾路徑,在任何平台都可以通過這個路徑讀取(qǔ)到文(wén)件夾裏的內容(róng)
Application.temporaryCachePath:臨時數據文件路徑
