绑定数据checkbox字符 Split返回的字符串进行分割
string[] Array = model.login_type.Split(',');

for (int i = 0; i < Array.Length; i++)
{
if (Array[i].Equals(txt_login_type.Value.Trim()))
{
txt_login_type.Checked = true;
}
if (Array[i].Equals(txt_login_type1.Value.Trim()))
{
txt_login_type1.Checked = true;

}
if (Array[i].Equals(txt_login_type2.Value.Trim()))
{
txt_login_type2.Checked = true;
}
if (Array[i].Equals(txt_login_type3.Value.Trim()))
{
txt_login_type3.Checked = true;
}
if (Array[i].Equals(txt_login_type4.Value.Trim()))
{
txt_login_type4.Checked = true;
}
}

更新保存数据

model.login_type = "";
if (txt_login_type.Checked)
{
model.login_type += txt_login_type.Value.Trim() + ",";
}
if (txt_login_type1.Checked)
{
model.login_type += txt_login_type1.Value.Trim() + ",";
}
if (txt_login_type2.Checked)
{
model.login_type += txt_login_type2.Value.Trim()+",";
}
if (txt_login_type3.Checked)
{
model.login_type += txt_login_type3.Value.Trim()+",";
}
if (txt_login_type4.Checked)
{
model.login_type += txt_login_type4.Value.Trim()+',';
}
Substring 截取字符串
model.login_type = model.login_type.Substring(0, model.login_type.Length - 1);
