type converter in c#?

You might want to use Integer.TryParse()

It can handle bad input better.

Usually if I have a text box that is strictly for numbers, I use the NumericUpDown control.

objective, Walmart, Radio Shack, or maybe maximum drug shops like CVS, Walgreens, and so on will carry effortless 50w converters/adapters. Walmart has a particularly finished set for $20. i'd be bowled over if perfect purchase did no longer have them.

Go thru this code....

using System;

using System.ComponentModel;

using System.Globalization;

using System.Drawing;

public class PointConverter : TypeConverter {

// Overrides the CanConvertFrom method of TypeConverter.

// The ITypeDescriptorContext interface provides the context for the

// conversion. Typically, this interface is used at design time to

// provide information about the design-time container.

public override bool CanConvertFrom(ITypeDescriptorContext context,

Type sourceType) {

if (sourceType == typeof(string)) {

return true;

}

return base.CanConvertFrom(context, sourceType);

}

// Overrides the ConvertFrom method of TypeConverter.

public override object ConvertFrom(ITypeDescriptorContext context,

CultureInfo culture, object value) {

if (value is string) {

string[] v = ((string)value).Split(new char[] {','});

return new Point(int.Parse(v[0]), int.Parse(v[1]));

}

return base.ConvertFrom(context, culture, value);

}

// Overrides the ConvertTo method of TypeConverter.

public override object ConvertTo(ITypeDescriptorContext context,

CultureInfo culture, object value, Type destinationType) {

if (destinationType == typeof(string)) {

return ((Point)value).X + "," + ((Point)value).Y;

}

return base.ConvertTo(context, culture, value, destinationType);

}

}

try using

order.price=Int.Parse(textbox.text);
