如何在C＃中将Int / Decimal转换为float？

Question

How does one convert from an int or a decimal to a float in C#?

I need to use a float for a third-party control, but I don't use them in my code, and I'm not sure how to end up with a float.

Answer 1

You can just do a cast

int val1 = 1;
float val2 = (float)val1;

or

decimal val3 = 3;
float val4 = (float)val3;

Answer 2

The same as an int:

float f = 6;

Also here's how to programmatically convert from an int to a float, and a single in C# is the same as a float:

int i = 8;
float f = Convert.ToSingle(i);

Or you can just cast an int to a float:

float f = (float)i;

Answer 3

You don't even need to cast, it is implicit.

int i = 3;

float f = i;

Answer 4

它只是：

float f = (float)6;
