Data Type Conversion In C#

Convert function in C# is used to convert an integer to string or string to integer or another format.

If you want data conversion in C#.net to follow the below steps. 

 

Step 1

 

Create an integer variable and assign integer value. Integer size is 4 bytes. 

int val=1235;

Step 2

 

Create a NULL string variable. The string is 2 bytes.

string str="";

Step 3

 

If I want to convert the integer to string we have to use this inbuilt function Convert.ToString(Parameter) and store this value as a string variable.

str=Convert.toString(Val);

Step 4

 

Above code output will be:

str="1235"

Step 5 

 

If you want to convert to another format, for example, string to int, int to float, float to string etc. 

//int32 and int16 this are used for 16 bit and 32 bit.
int temp=Convert.Int32(str);
//or
int temp=Convert.Int16(str);

If you want to convert data in another format then you can use Convert.toInt32().

 

Integer to char

 

In the below code we see conversion from integer to String.

int a=123;
String str=Convert.toString(a);
output
"123"

Char to Integer

 

In the below code conversion from string to integer. 

string str="1234";
int val=Convert.toInt32(str);
output
1234

Integer to Float

 

The below code shows Integer to float data type conversion. 

int a=12;
float val=Convert.ToSingle(a);
output
12.00

Int to Double

 

The below code is int to double data type conversion. 

int val=54;
Double d=Convert.ToDouble(val);
output
54.00

Float to Double

 

The  below code is  float to double data type conversion. 

float f=1.5f;
Double val=Convert.ToDouble(f);
output
1.500
