Filename is empty in SaveDialogue

I am trying to save a xml file generated in the code using Savedialogue.

I have given the following code in my click button command.

var saveDialog = new Microsoft.Win32.SaveFileDialog()

{

Filter = "Loan Parameters(*.xml)|"

};

if (saveDialog.ShowDialog() == false)

{

return;

}

// XML Serialization and Binary Encoding

byte[] buffer = LoanDataHelper.SerializeModel(loanParameterValueConfig);

if (buffer != null)

{

LoanDataHelper.WriteStreamToFile(buffer, saveDialog.FileName, LoanDataHelper.FileFormat.Normal);

}

I am using mvvm model .On running I am getting exception as filename is not getting the value that I am passing in the savedialogue window.It is always empty string.

I could not figure out what i am missing here.

Please help.

Thanks in advance

Checking only whether the object is false does not end the requirement. You have to check whether there was successful file selection event or not.

To do that you are required to check the result of this dialog also. If it is OK or if the file exists in the object then continue and get the FileName. Otherwise, skip the code. Like this,
```
if(saveDialog.CheckFileExists) {
   // File is present... 
   // Write your remaining code here..
}
```
Now the code would not throw this error. Because it would only execute if there is a file available in the object. For more on this object, please go to MSDN and read the documentation.

Hello Dipankar, I have used the same thing as mentioned in the link.But the FileName is coming as empty.I couldnt find the reason why it is coming as empty though I am giving the name in the dialogue opened. Thanks
