ObjectDisposedException: Cannot write to a closed TextWriter.
时间: 2024-05-10 22:20:28 浏览: 13
This exception occurs when you try to write to a TextWriter object that has already been closed. Once a TextWriter object is closed, it cannot be used to write any further data.
To avoid this exception, check if the TextWriter object is closed before attempting to write to it. Alternatively, you can create a new TextWriter object and write to it instead.
Here is an example code snippet that shows how to check if a TextWriter object is closed:
```
TextWriter writer = new StreamWriter("file.txt");
// Write some data to the file
writer.Write("Hello World!");
// Close the writer
writer.Close();
// Attempt to write again
try
{
writer.Write("This will throw an ObjectDisposedException");
}
catch (ObjectDisposedException ex)
{
Console.WriteLine(ex.Message);
}
```
In the above example, the TextWriter object is closed before attempting to write to it again, which results in an ObjectDisposedException being thrown.
