difference between convert.tostring() and Tostring()

yes Mohan Arumugam, not a problem nothing wrong in your code but we are going to handling null or string.empty in string declaration incase string value cleared your code that time we will get the error.

 

pls check and see the difference

 

string strname=null;

if(string.isNullorEmpty(strname))

it's getting error

but 

if(string.isNullorEmpty(Convert.Tostring(strname)))//it handle the null value

can u tell whats wrong in it

 

int i =0;

MessageBox.Show(i.ToString());

MessageBox.Show(Convert.ToString(i));

 

We can convert the integer “i” using “i.ToString()” or “Convert.ToString” so what’s the difference.

 

The basic difference between them is “Convert” function handles NULLS while “i.ToString()”

does not it will throw a NULL reference exception error. So as good coding practice using

“convert” is always safe.

The basic difference between them is “Convert.ToString(variable)” handles NULL values even if variable value become null but “variable.ToString()” will not handle NULL values it will throw a NULL reference exception error. So as a good coding practice using “convert” is always safe.

 

Example

I hope it helps.
