vb.net - 有谁知道为什么这个应用程序在执行存储过程时会超时？

Question

我一直在尝试执行存储过程，但每次单击从我的应用程序执行它时，它都会超时并出现以下错误：

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

如果需要对下面的例程进行任何更改，有什么想法吗？

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

非常感谢

您的 CommandTimeout 可能在调用完成之前到期，试试这个：

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
