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; 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 public static string GetCSVFormat(string str) { 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 if (line == "") { Fields.Add(""); } // Iterate through every character in the line for (int i = 0; i < line.Length; i++) { char character = line[i]; // If we are not currently inside a column if (!inColumn) { // If the current character is a double quote then the column value is contained within // double quotes, otherwise append the next character inColumn = true; if (character == '"') { inQuotes = true; continue; } } // If we are in between double quotes if (inQuotes) { if ((i + 1) == line.Length)//這個字符已(yǐ)經結束了整行 { if (character == '"') //正常轉義結束,且該行已經結束 { inQuotes = false; continue; //當前字符不用(yòng)添加,跳(tiào)出後直結束後會添加該元素 } else //異常結束,轉義未收尾 { isNotEnd = true; } } else if (character == '"' && line[i + 1] == _csvSeparator) //結束轉義,且後麵有(yǒu)可能還有(yǒu)數據 { inQuotes = false; inColumn = false; i++; //跳(tiào)過下(xià)一個字符 } else if (character == '"' && line[i + 1] == '"') //雙引號轉義(yì) { i++; //跳過下一個字符(fú) } else if (character == '"') //雙引號單獨出現(這種情況實際上已(yǐ)經是格式錯(cuò)誤(wù),為了(le)兼容可暫時不處理) { throw new Exception("格式錯(cuò)誤,錯誤(wù)的雙引號轉義"); } //其他情況直接跳出,後麵正常添加(jiā) } else if (character == _csvSeparator) inColumn = false; // If we are no longer in the column clear the builder and add the columns to the list if (!inColumn) //結束該元素時(shí)inColumn置為false,並且(qiě)不處理當(dāng)前字符,直接進(jìn)行Add { Fields.Add(_trimColumns ? _columnBuilder.ToString().Trim() : _columnBuilder.ToString()); _columnBuilder.Remove(0, _columnBuilder.Length); } else // append the current column _columnBuilder.Append(character); } //(標準格式一行結尾不需要逗號結尾,而上麵for是遇到逗號才添加的,為了(le)兼容還要添加一次)
if (inColumn) { if (isNotEnd) { _columnBuilder.Append("\r\n"); } Fields.Add(_trimColumns ? _columnBuilder.ToString().Trim() : _columnBuilder.ToString()); } else //如果inColumn為false,說明已經添加,一個字符為分隔符,所以後麵要加上一個空(kōng)元(yuán)素 { Fields.Add(""); } return Fields; } //讀取文件(jiàn) public static ListRead(string filePath, Encoding encoding) { Listresult = new List(); string content = File.ReadAllText(filePath, encoding); string[] lines = content.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries); for (int i = 0; i < lines.Length; i++) { Listline = ParseLine(lines[i]); result.Add(line); } return result; } //寫入(rù)文件 public static void Write(string filePath, Encoding encoding, Listresult) { StringBuilder builder = new StringBuilder(); for (int i = 0; i < result.Count; i++) { Listline = result[i]; builder.Append(GetCSVFormatLine(line)); } File.WriteAllText(filePath, builder.ToString(), encoding); } //打印 public static void Debug(Listresult) { for (int i = 0; i < result.Count; i++) { Listline = result[i]; for (int j = 0; j < line.Count; j++) { UnityEngine.Debug.LogWarning(line[j]); } } } }
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
