如何将字符串转换为int和十进制 [英] how to convert string to int and decimal

问题描述

你好
我正在尝试这样做:将文本框的值等于emp类属性类型int和十进制

 txtDept.text = emp.DepID // 字符串= int 
txtSalary.text = emp.salary // 字符串=十进制
 
解决方案
 
请参阅以下内容:



 ^ ] 





 字符串 a = "  字符串 a = "  字符串到 int 
使用=
Convert.ToInt32(字符串)

字符串为十进制
Convert.ToDecimal(字符串); 
 
 
 
使用具有所需格式的ToString 方法，如下所示:

 txtDept.Text = emp.DepID.ToString();
txtSalary.Text = emp.salary.ToString(" ); 
 

问题尚不清楚.如果需要将数字的string表示转换为其原始值，则有几种方法.一种选择是使用Convert.ToInt32, Convert.ToDecimal等方法，因为即使输入值是null ，这些方法也不会throw exception，如下所示:

 emp.DepID = Convert.ToInt32(txtDept.Text);
emp.salary = Convert.ToDecimal(txtSalary.Text); 
 
 
 
Hello

string a = "1234″;

int b = Convert.ToInt16(a);






string a = "1234.34″;
decimal b = decimal.Parse(a);

String to int
use=
Convert.ToInt32(string)

String to Decimal
Convert.ToDecimal(String);

Use the ToString method with required format as shown below:

txtDept.Text = emp.DepID.ToString();
txtSalary.Text = emp.salary.ToString("N2");


The question was not clear.  If it is required to convert the string representation of the number to its native value then there are several approaches.  One option is to use Convert.ToInt32, Convert.ToDecimal etc. methods as these will not throw exception even when the input value is null as shown below:

emp.DepID=Convert.ToInt32(txtDept.Text);
emp.salary=Convert.ToDecimal(txtSalary.Text);
