I am unable to read the text file in windows form . i am getting the following error

An unhandled exception of type 'System.NotSupportedException' occurred in mscorlib.dll

Additional information: The given path's format is not supported.

I had written like this:

String^ strfilename = openFileDialog1->InitialDirectory + openFileDialog1 + filename;

String^ readfile = File::ReadAllText(strfilename);

can anyone tell me what I could do

Know the answer? Post it — somebody with the same question will find it here.

It is the same account you read, post and publish with — and you will come straight back to this page.

Hi,

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog; //to open a dialog box
if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
{
StreamReader^ sr = gcnew StreamReader(openFileDialog1->FileName);

MessageBox::Show(sr->ReadToEnd());
sr->Close();
}
}
