The configuration file could not be parsed.

The Reset method overwrites the user-scoped settings properties by restoring the currently persisted value of each application settings. This method performs the following actions:

Reload contrasts with Reset in that the former will load the last set of saved application settings values, whereas the latter will load the saved default values.

The following code example shows the Reset method being invoked in the body of the Click event handler for a button named btnReset. As a result of this call, the stored default values for the application settings are reloaded into their corresponding properties. The full code example is listed in the ApplicationSettingsBase class overview.

private void btnReset_Click(object sender, EventArgs e)
    this.BackColor = SystemColors.Control;
