Is there a maximum number of characters that can be written using a StreamWriter?
提问by Josh Mein
Is there a maximum number of characters that can be written to a file using a StreamWriter? Or is there a maximum number of characters that WriteLine()can output? I am trying to write some data to a file but all of the data does not seem to make it. This is the current state of my code:
是否有使用 StreamWriter 可以写入文件的最大字符数？或者有WriteLine()可以输出的最大字符数吗？我正在尝试将一些数据写入文件，但所有数据似乎都没有写入。这是我的代码的当前状态：
StreamWriter sw = new StreamWriter(pathToFile);
foreach (GridViewRow record in gv_Records.Rows)
{
string recordInfo = "recordInformation";
sw.WriteLine(recordInfo);
}

Are you calling StreamWriter.Close() or Flush()?
你是在调用 StreamWriter.Close() 还是 Flush()？
回答by user7116
Be sure you wrap your StreamWriter in a using-block, or are careful about your explicit management of the resource's lifetime.
确保将 StreamWriter 包装在 using 块中，或者小心您对资源生命周期的显式管理。
using (StreamWriter writer = new StreamWriter(@"somefile.txt"))
{
// ...
writer.WriteLine(largeAmountsOfData);
// ...
}

Make sure that you are calling .Flush()
确保您正在调用 .Flush()
