I have form and in this form I have two date fields, campodata1 is populated by user and campodata2 is filled by the database, now I need a code to compare if these two fields have the same information.
The fields are string I'm even using in form the masktext for date fields, I just need to compare to see if they are the same to do an action.
Follow an image of my form
What you can do is simply convert the dates in STRING format to DATETIME and make a normal comparison:
DateTime data1 = Convert.ToDateTime(CampoData1.text);
DateTime data2 = Convert.ToDateTime(CampoData2.text);
if (data1 > data2)
{
/*...*/
}
else if (data1 == data2)
{
/*...*/
}
else if (data1 < data2)
{
/*...*/
}
using System;
public class Example
{
public static void Main()
{
DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;
if (result < 0)
relationship = "é mais nova que";
else if (result == 0)
relationship = "é igual a";
else
relationship = "é depois de";
Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
}
}

The accepted solution will break the application whenever someone enters a wrong format, so it works:
if (!datetime.TryParse(CampoData1.text, out var data1)) //faz o tratamento de erro aqui
if (!datetime.TryParse(CampoData2.text, out var data2)) //faz o tratamento de erro aqui
//só pode ir pra frente aqui se não houve erro acima
if (data1 > data2) //faz algo para o maior
else if (data1 < data2) //faz algo para o menor
else //faz algo para o igual
