Use of unassigned local variable 'name'

The C# compiler does not allow the use of uninitialized variables. If the compiler detects the use of a variable that might not have been initialized, it generates CS0165.

string Sample;

Nullable <bool> FlagComplete = null;

if (FlagComplete.HasValue)

{

MessageBox.Show(Sample);

}

Use new to create an instance of an object or assign a value

string Sample = "";

Nullable <bool> FlagComplete = null;

if (FlagComplete.HasValue)

{

MessageBox.Show(Sample);

}

else

If you want to have null for the variable Sample, declare it as Nullable ()
