what is the difference between these two conversions

Question

convert.toint23('asdf'.tostring());==>this shows exception why convert.toint32('asd');

Vinay Singh · Answer

Hi In both cases you will get exception. Region you are converting a text into number Here is the correct example string data=Test; string value1=Convert.ToString(data); // This will allow null value string value2=data.ToString();// This will not accept null value

Hi Shiva First of all syntax is wrong in both cases. convert.toint23('asdf'.tostring()); convert.toint32('asd'); In both cases you will get a runtime exception. Convert.ToInt32(asdf.ToString()); Convert.ToInt32(asdf); Please see the below link . https://msdn.microsoft.com/en-us/library/sf1aw27b(v=vs.110).aspx If the above solution is helpful then accept the answer.
