我现在使用 StreamReader 更改了 button2 点击事件，因此它将 ReadToEnd();拆分目录中的每个文本文件。

但它不起作用，它不读取结束文件。

我遇到错误：r = new StreamReader(fi[i].ToString());

错误提示：FileNotFoundException: 找不到文件 'D:\C-Sharp\Google_Translate\Google_Translate\Google_Translate\bin\Debug\File0000.txt'。

文本文件在 d:\testsplit

无法弄清楚为什么它试图从 C-Sharp...目录而不是 d:\testsplit 读取文件

下面是修改片段的代码：

        if (result1 == DialogResult.OK)
        {
            SplitFiles(file1, 1024 * 32, splitDirectory);
            dir1 = new DirectoryInfo(splitDirectory);
            fi = dir1.GetFiles("*.txt");
            StreamReader r;
            for (int i = 0; i < fi.Length; i++)
            {
                r = new StreamReader(fi[i].ToString());
                string y = r.ReadToEnd();
                t.SourceLanguage = comboBox1.Text;
                t.TargetLanguage = comboBox2.Text;
                t.SourceText = y;
                t.Translate();
            }
            CombineFiles(@"d:\testsplit\newFileTranslated.txt", splitDirectory); // to change string newlargeFile to a new file name or the same file the user will select if the same name change file name and which directory to
            // save the file to using the current format sample in the CombineFile function \\
            // to check why its not translating the small files inside the for loop before combining them \\ 
            button1.Enabled = true;
        }

Answer 1

我想你需要

• 将 working directory 更改为包含文件的目录

  Environment.CurrentDirectory = @"d:\testsplit";
  

• 或在文件名前添加路径（使它们成为绝对路径@"d:\testsplit\test.txt"）
