implicite conversion rule in c# 4.0

Question

0.00/5 (No votes)

See more:

When one type of data is assigned to another type an implicit conversion will take place automatically if

1>The two types are compatible

2>Destination type has a range that is greater than sourse type.
(reference from c# 4.0 complete reference.by Herbert Schildt)

Now following this rule
char ch;
ushort vushort;
ch=vshort; //error:implicit conversion not from ushort to char

Now my question is that:
char is an unsigned 16 bit data.And ushort also unsigned 16 bit depth.
then why implicite conversion not possible.

Give answer in accordance to rule stated above..

Hi rtn,

This is a tricky question. Still, there is no implicit numeric conversion defined for ushort to char. The only valid thing is vice-versa, from char to ushort.
In short, there are no implicit conversions to char type, so the values of the other integral types do not automatically convert to the char type.

The implicit numeric conversions are:

From sbyte to short, int, long, float, double, or decimal.

From byte to short, ushort, int, uint, long, ulong, float, double, or decimal.

From short to int, long, float, double, or decimal.

From ushort to int, uint, long, ulong, float, double, or decimal.

From int to long, float, double, or decimal.

From uint to long, ulong, float, double, or decimal.

From long to float, double, or decimal.

From ulong to float, double, or decimal.

From char to ushort, int, uint, long, ulong, float, double, or decimal.

From float to double.

For example, this will work just fine:

C#

char ch = '1';
ushort vushort;
vushort = ch;

Hope this helps.

Cheers
