如何修复涉及 System.IO.File 成员函数的 UNITY 3D 项目中的 JavaScript 错误？

Question

我在这里有一个函数来存储块的坐标。看起来不错，但控制台给了我这个错误：

BCE0019: 'WriteLine' is not a member of 'System.IO.StreamReader'

如果您知道如何解决此问题，我将不胜感激。

function writeChunks(fileName : String, xco : int, yco : int, zco : int) {
    var sr = System.IO.File.OpenText(fileName);
    sr.WriteLine("Chunk ("
                    + xco + ", " 
                    + yco + ", " 
                    + zco + ")");
    sr.Close();
}

更新 1 这段代码：

 function writeChunks(fileName : String, xco : int, yco : int, zco : int) {
    var sr = System.IO.File.OpenText(fileName);
    System.IO.File.WriteAllText("C:/youfilename.txt", "Chunk ("
                + xco + ", " 
                + yco + ", " 
                + zco + ")");
    sr.Close();
    }

给我这个错误：

    DirectoryNotFoundException: Could not find a part of the path "C:\Reactor Games\chunks.txt".

更新 2 这段代码：

function writeChunks(fileName : String, xco : int, yco : int, zco : int) {
    var sw = new StreamWriter("fileName"); 
    sw.WriteLine("Chunk ("
                + xco + ", " 
                + yco + ", " 
                + zco + ")");  
    sw.Close();
}

给我这个错误：

BCE0005: Unknown identifier: 'StreamWriter'.

如果您可以为方便添加一个 C# 类，那么您可以调用它。但似乎你也可以将它与 JavaScript 一起使用：

还要确保您的目录存在：

System.IO.File.WriteAllText(filepathIncludingFileName, "Chunk ("
                + xco + ", " 
                + yco + ", " 
                + zco + ")");

我还检查了其他地方，有些人提到你可以在 JavaScript 部分使用 StreamWriter 类：

var sw : StreamWriter = new StreamWriter(filepathIncludingFileName);
sw.WriteLine("Line to write");
sw.WriteLine("Another Line");
sw.Flush();
sw.Close();

很遗憾，我在 Unity3D 脚本 API 文档中找不到此信息。您应该谨慎使用它。
