我现在使用StreamReader更改了button2 click事件，因此它将ReadToEnd（）;分割目录中的每个文本文件。
但它不起作用，它不会读取文件结束。
我在线上得到错误：r = new StreamReader（fi [i] .ToString（））;
错误说：FileNotFoundException：找不到文件'D：\ C-Sharp \ Google_Translate \ Google_Translate \ Google_Translate \ bin \ Debug \ File0000.txt'。
文本文件位于d：\ testsplit
无法弄清楚为什么它试图从C-Sharp ...目录中读取文件而不是d：\ testsplit
以下是更改过的片段的代码：
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;
}
答案 0 :(得分：0)
我想你需要
将 working directory 更改为包含文件的目录
Environment.CurrentDirectory = @"d:\testsplit";
或预先添加文件名的路径（将它们设为绝对@"d:\testsplit\test.txt"）
