Convert string to integer..

[Vandy02]

i am trying to covert a string to an integer....
I have tried v_counting = Convert.ToInt32(ENAME.Text);

but I keep getting errors..not in correct format....

Hmm ENAME does not sound like a likely name for an integer.

What is in ENAME just before
v_counting = Convert.ToInt32(ENAME.Text);

Try this

string strVariable = "3";

int intvariable = Convert.ToInt16( strVariable );

Be aware that an empty string ("") in the textbox will also cause the error.

Good point:

string strVariable = "3";
int intVariable = 0;

if ( strVariable == "" )
{
strVariable = "0";
intVariable = Convert.ToInt16( strVariable );
}
else
intVariable = Convert.ToInt16( strVariable );

The VB.NET to C# converter Instant C# makes a static class available to mimic the robustness of the VB cast macro "CInt":

internal static int CInt(object oValue)
{
try
{
if (oValue == null || System.Convert.IsDBNull(oValue))
//default null to 0 (identical to the VB.NET cast):
return 0;

double dValue;
if (double.TryParse(oValue.ToString().Trim(),
NumberStyles.Any, CultureInfo.CurrentCulture, out dValue))
if (dValue <= int.MaxValue && dValue >= int.MinValue)
return (int)(System.Math.Round(dValue));
else
return 0;
else
return 0;
}
catch
{
return 0;
}
}

could you not do a Int.Parse(string)

If you pass in a non-integer compatable string to Int.Parse, it will throw a System.FormatException.

So long as the Parse operation is handled within a try .. catch block then problems can be dealt with.
