在 C# 中附加到 Avro 文件

Question

我想将数据附加到 Avro 文件。数据与 Avro 文件的其余部分具有相同的架构。我看到 Java 的 appendTo 方法似乎可以做到。有没有办法让我在 C# 中做到这一点？

Answer 1

见File.AppendText

来自文档的示例：

    string path = @"c:\temp\MyTest.txt";
    // This text is added only once to the file.
    if (!File.Exists(path))
    {
        // Create a file to write to.
        using (StreamWriter sw = File.CreateText(path))
        {
            sw.WriteLine("Hello");
            sw.WriteLine("And");
            sw.WriteLine("Welcome");
        }   
    }

    // This text is always added, making the file longer over time
    // if it is not deleted.
    using (StreamWriter sw = File.AppendText(path))
    {
        sw.WriteLine("This");
        sw.WriteLine("is Extra");
        sw.WriteLine("Text");
    }   

    // Open the file to read from.
    using (StreamReader sr = File.OpenText(path))
    {
        string s = "";
        while ((s = sr.ReadLine()) != null)
        {
            Console.WriteLine(s);
        }
    }
