Problema creando archivo .txt

[lisseth]

hola a todos, estoy creando un archivo .txt en con el siguiente codigo:


Dim strStreamWriter As StreamWriter

Dim strStreamW As Stream

Dim FilePath As String = "Archivo.txt"

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim filename As String = Server.MapPath("~/mensaje/errores/" + FilePath)

strStreamW = File.OpenWrite(filename)

strStreamWriter = New StreamWriter(strStreamW, System.Text.Encoding.UTF8)



strStreamWriter.Close()

strStreamW.Close()

pero me sale el siguiente error cuando lo ejecuto:



Server Error in '/pca_z' Application.
