The Smartstore DefaultTypeConverter and StringExtensions methods pose some challenges and might need optimization.

https://github.com/smartstore/Smartstore/blob/5.1.0/src/Smartstore/ComponentModel/TypeConverters/DefaultTypeConverter.cs https://github.com/smartstore/Smartstore/blob/5.1.0/src/Smartstore/Extensions/StringExtensions.Conversion.cs

https://github.com/smartstore/Smartstore/blob/5.1.0/src/Smartstore/Utilities/ConvertUtility.cs

• The program is throwing too many exceptions, which could actually be handled effectively. https://github.com/smartstore/Smartstore/issues/1085

For example, the code below:

//ConvertUtility.TryConvert
[MethodImpl(MethodImplOptions.AggressiveInlining)]
public static int ToInt(this string? value, int defaultValue = 0)
{
    if (ConvertUtility.TryConvert(value, typeof(int), CultureInfo.InvariantCulture, out object? result))
    {
        return (int)result!;
    }

    return defaultValue;
}

If the code is modified like this, would there be any impact on performance, considering not throwing exceptions?

[MethodImpl(MethodImplOptions.AggressiveInlining)]
public static int ToInt(this string? value, int defaultValue = 0)
{
    if (string.IsNullOrEmpty(value))
    {
        return defaultValue;
    }

    if (int.TryParse(value, NumberStyles.Integer, CultureInfo.InvariantCulture, out int result))
    {
        return result;
    }

    return defaultValue;
}

There might be issues with the code here, such as exceptions or incorrect recognition.

        public virtual object ConvertFrom(CultureInfo culture, object value)
        {
            if (value != null && value.GetType() == _type)
            {
                return value;
