vb.net - ストアド プロシージャの実行時にこのアプリがタイムアウトする理由を知っている人はいますか?

Question

ストアド プロシージャを実行しようとしましたが、クリックしてアプリから実行するたびに、次のエラーでタイムアウトします。

Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

以下のルーチンで何か変更する必要がある場合、何かアイデアはありますか?

Private Sub Reset()
    Dim connectionString As String = ConfigurationManager.ConnectionStrings("constring").ConnectionString
    Dim storedProcName As String = "insertnewSP"
    Dim conn As SqlConnection = New SqlConnection(connectionString)
    conn.Open()
    Dim command As SqlCommand = New SqlCommand(storedProcName, conn)
    command.CommandType = CommandType.StoredProcedure
    command.ExecuteNonQuery()
    command.Dispose()
    conn.Close()
    conn.Dispose()
End Sub
Protected Sub Refresh_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Refresh.Click
    ' Clean up text to return the Gridview to it's default state
    Reset()
    strsearch.Text = ""
    SearchString = ""
    gridView1.DataBind()
End Sub

どうもありがとう

呼び出しが完了する前に CommandTimeout が期限切れになる可能性があります。これを試してください。

Private Sub Reset()
    Dim connectionString As String = ConfigurationManager.ConnectionStrings("constring").ConnectionString
    Dim storedProcName As String = "insertnewSP"
    Dim conn As SqlConnection = New SqlConnection(connectionString)
    conn.Open()
    Dim command As SqlCommand = New SqlCommand(storedProcName, conn)
    command.CommandType = CommandType.StoredProcedure
    command.CommandTimeout = 180
    command.ExecuteNonQuery()
    command.Dispose()
    conn.Close()
    conn.Dispose()
End Sub

Protected Sub Refresh_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Refresh.Click
    ' Clean up text to return the Gridview to it's default state
    Reset()
    strsearch.Text = ""
    SearchString = ""
    gridView1.DataBind()
End Sub
