Addition of int and uint

Question

I\'m surprised by C# compiler behavior in the following example:

int i = 1024;
uint x = 2048;
x = x+i;     // A error CS0266: Cannot implicitly convert type          


        

Answer 1

i        int i = 1024;
uint x = 2048;
// Technique #1
    x = x + Convert.ToUInt32(i);    
// Technique #2
    x = x + checked((uint)i);
// Technique #3
    x = x + unchecked((uint) i);
// Technique #4
    x = x + (uint)i;
